9019 Ziegler Mahal Rug 13 ft 6 in x 23 ft (411 x 701) A wonderful example from Ziegler & Company, a British based firm producing carpets in late 19th century Persia. This piece is in remarkable condition given the fact that it was in the private collection of a renowned American dealer for over 50 years before we acquired it in the 1990’s.
