What Rug Labels and Signatures Mean: Origin Marks, Cartouches and Exhibition Medals

When examining a rug for the first time, most people focus on the front. A specialist examines the back, the edges, and looks closely at any labels or markings. These can range from highly informative to entirely generic — and knowing the difference matters when assessing what you have.

Labels and markings fall into several distinct categories, each with different implications for authenticity and value.

Woven Cartouches

A cartouche is a woven inscription panel within the rug itself — part of the design, not something added later. Cartouches are found primarily in Persian city rugs from named workshops: Kashan, Tabriz, Isfahan, and occasionally Qom and Mashad.

A cartouche typically appears in the main border, at the end of a central medallion, or within the field. The inscription is usually in Arabic or Persian script (Nasta'liq or Naskh calligraphic style) and may contain:

• The weaver's or workshop master's name: "Amal-e [Name]" — "Work of [Name]". Named workshop rugs are among the most collected category in the Persian tradition. Known masters such as Mohtasham of Kashan command significant premiums.
• A dedicatory inscription: The rug was made as a gift or commission for a specific patron. These are historically significant and add substantial provenance.
• A date: Woven dates are discussed separately below.
• A verse or religious phrase: Particularly in prayer rugs and fine formal pieces.

Because cartouches are woven into the structure of the rug, they cannot be added later. A cartouche from a named workshop is among the most reliable forms of provenance a rug can carry. However, skilled reproductions of famous workshop styles do exist, so the cartouche must be assessed alongside the rug's overall construction quality and physical characteristics.

Woven Dates

Some rugs contain a woven date within a cartouche or within the border. These are almost always given in the Islamic lunar calendar (Hijri calendar), which began in 622 CE. To convert a Hijri date to a Gregorian date approximately: multiply the Hijri year by 0.97 and add 622.

For example, a rug dated 1310 AH would correspond approximately to 1892–1893 CE (1310 × 0.97 + 622 ≈ 1893).

Important caveats about woven dates:

• Not all woven dates are accurate. A weaver may have inserted an aspirational or auspicious date, or copied a date from an earlier piece they were replicating.
• Some dates are genuinely miscalculated — calendar conversion errors are not uncommon.
• Later reproduction pieces sometimes copy dates from originals. The physical characteristics of the rug should be consistent with the claimed date.

A woven date that is consistent with the rug's dye characteristics, pile condition, and foundation materials is significant supporting evidence for age. An inconsistency between claimed date and physical condition should prompt careful assessment.

Paper and Cloth Labels

Many rugs carry paper or cloth labels sewn to one corner of the reverse. These were almost always added by importers, dealers, or auction houses — not by the original weavers.

What these labels may contain:

• Origin statement: "Persian Kashan", "Turkish Hereke", "Antique Caucasian" — useful but not independently verifiable from the label alone.
• Importer details: Companies such as Ziegler & Co., Hotz & Son, or Liberty of London imported large quantities of Persian rugs in the late 19th and early 20th centuries. A label from one of these respected importers adds genuine provenance.
• Auction lot numbers: Labels from Bonhams, Christie's, Sotheby's, Rippon Boswell (specialist rug auction), or other houses indicate the rug was previously sold through a specialist marketplace. The lot number can often be used to retrieve the original sale catalogue, establishing a documented price history.
• Size and condition notes: Added by dealers for inventory purposes. Minimally informative but confirm the piece was handled by a trader at some point.

When paper labels add genuine value

An auction house label from a specialist sale is significant. It means the rug was assessed by qualified people, judged worth including in a specialist sale, and sold in a competitive marketplace. The rug has a documented history. This is particularly valuable for pieces where physical dating is uncertain, as it establishes a terminus ante quem — the rug existed and was old enough to sell at specialist auction by a known date.

When paper labels add minimal value

A generic retailer label — "Persian rug", "Made in Iran", "Oriental carpet" without specific detail — adds little. These were typically applied at the point of retail sale and reflect only that the rug was sold through a shop at some point. They are not expert assessments.

Exhibition Medals and Stamps

The great international exhibitions of the 19th century — Vienna 1873, Paris 1878, Philadelphia 1876, Chicago 1893, Paris 1900 — included significant collections of oriental rugs among their exhibits. Exceptional pieces displayed at these exhibitions sometimes carry evidence of that exhibition: sewn fabric medals, paper stamps, or exhibition catalogue references.

Genuine exhibition pieces are rare. When they are authentic, they represent some of the finest examples of 19th-century weaving — selected as best-in-class by the international trade at the time. An authenticated exhibition rug commands a very significant premium.

However, exhibition medals and stamps can be fabricated or transferred. Any claim of exhibition provenance should be supported by documentary evidence — catalogue records, exhibition correspondence, or consistent physical characteristics confirming 19th-century manufacture.

Modern Certification Labels

A number of contemporary certification schemes apply labels to modern hand-knotted rugs:

• DOBAG: Turkish cooperative founded in 1981, certifying natural dye use in hand-knotted rugs. A DOBAG label on a Turkish rug is a genuine quality guarantee for modern production.
• STEP (Sustainable Textile of the Eastern Hemisphere): A fair trade and child-labour-free certification used by some Moroccan and Central Asian producers. Relevant for contemporary rugs; does not apply to antiques.
• GoodWeave: A child labour certification used in Nepal, India, and Afghanistan. Again, relevant for modern production.

These labels affect contemporary hand-knotted rugs more than antiques — they are market differentiators for modern production, not historical provenance indicators.

Red Flags: Labels That Mislead

• "100% Persian Rug" on a machine-made piece: Some mass-produced machine-made rugs carry generic labels implying Persian origin or quality. The physical construction of the rug — not the label — determines what it actually is.
• Generic "Oriental carpet" tags: These may have been added by a retailer who had no specialist knowledge of the piece. They describe an aesthetic category, not an origin.
• Handwritten or typed labels without institutional attribution: A label that says "Antique Persian 1890" in handwriting tells you only that someone wrote that at some point — not that it is accurate.

When Labels Add Value vs When They Don't

To summarise the hierarchy of label value:

• High value: Woven cartouche from a named master weaver or recognised workshop; specialist auction house label with retrievable lot record; documented exhibition medal with supporting documentary evidence.
• Moderate value: Reputable importer label (Ziegler, Liberty, etc.); regional auction house label; paper label consistent with physical assessment from a known dealer.
• Low value: Generic retailer label; handwritten attribution without institutional backing; modern certification labels on pieces claimed to be antique.
• Potential red flag: A label inconsistent with the rug's physical characteristics; a generic "Persian" label on a piece whose reverse shows machine-made construction.
