The 'Lotto' field design of this fragment is highly unusual. The usual colour combination is a yellow lattice on a red ground; the blue lattice on the present lot is rarely seen. A carpet with this palette can be seen in Alexander. C., A Foreshadowing of 21st Century Art The Color and Geometry of Very Early Turkish Carpets' New York, 1993, p. 217. For further information on 'Lotto' carpets see lot 122 in this sale.
