Lambert, Professor of Assyriology at the University of Birmingham, 1970-1993, which states: 'On the left is a seated figure on an angular stool raising one hand. On the right is a standing figure raising one hand. Both wear long robes. Between them is a table with a bread on top. There is a crescent in the sky and a tree or branch as a terminal. This is a Post Akkadian seal from southern Mesopotamia, c. 2200-2100 B.C. It is joined from fragments, but is complete and save for the breaks in good condition.' 5.7 grams, 21mm (1").
