23rd-20th century BC. A bronze discoid stamp with openwork design, accompanied by a typed and signed note by W.G. Lambert, late Professor of Assyriology, University of Birmingham, 1970-1993, which states: 'Stamp Seal of Bronze, 75 x 74 x 16mm. This is round, compartmented and open-work. On the flat back is a loop handle of inverted V-shape. The flat face has a small circle in the middle, and four other such circles forming a square between the centre and the edges. Each of the four circles has around it a rough square with zig-zag sides, reaching from the similar square around the central circle to the outer band. This has a simple circular edge on the inside, and a scalloped edge on the outside. This seal comes from west central Asia, and dates to c. 2300-2000 B.C. It is exceptionally large, and in very good condition, save for damage to one of the outer scallops. It is a fine piece.' 103 grams, 73mm (3"). The Signo collection, the property of a West London businessman, formed in the late 1980s-early 1990s; collection number N-1, academically researched and catalogued by the late Professor Lambert in the early 1990s.
