Gift of Milton Girod-Nr.1988.243

Postscript 4 April 2023:

The carpet was returned by Myers to the seller Paul Mallon,after the admonitions of Maurice Dimand,who considered it a fake.Mallon`s stepson Milton Girod-Mallon donated it to the Cleveland Museum of Art,where it still slumbers,considered for a long time to be a 15th century Persian rug.

After careful dye analysis in 2018 the rug was proven to be a later example containing dyes which were first invented in the late 19th century.

Photos of the rug`s back on the Cleveland website reveal it to possess a structure not unlike Tibetan carpets,positing an origin somewhere in Central-Asia (Uzbek Julkhyr carpets also employ such a technique)It probably has a Persian knot.

If it is a fake the question is:of what?
