Koller Auction, Zurich, 30 May 1987. sold for $16,286 (Lot no: 1809)
Hali Notes: "Despite its high price, this rug caused some controversy.
A comparison with the copy of Von Angeli/Bode prayer rug in the Keir
Collection, published in Spuhler's catalogue, no:28, is disconcerting. The
Von Angeli/Bode rug is lacking its main borders and the weavers of
all subsequent versions made their copies with two guards only, without
apparently realising their mistake.
