This rug has the characteristic blue selvege and colors of Seichour rugs. It has an unusual bird border and a fine weave, of approximately 130 kpsi. Its Kasim Ushag design (usually seen in Karabagh rugs) derived from 17th century Caucasian embroideries. This rug is a very close match with the Seichour rug in Raoul Tschebull article, Hali 62, page 84. Field clearly derived from early Caucasian workshop carpets while the medallion is reminiscent of early Caucasian embroideries such as the one on page 106 of this same issue.
