Ian Bennett's Oriental Rugs Volume I

pl. 409 An interesting rug, the long narrow field of which has a composition closely related to some so-called Chichi rugs. The bold and handsome
border is characteristic of a group of long rugs usually attributed by authors to Daghestan. Perhaps the most beautiful example in recent
literature is a rug with an open blue field surrounded by a bold red serration illustrated by Eberhart Herrmann in Von Lotto bis Tekke (no. 31), a piece
which could possibly be late 18th century in date. However, a very similar border is also found on later Shirvan long rugs — compare, for instance 255. Probably second half of the 19th century.
