Square tapering seal made from buffalo horn. There are no inscription but we believe that the seal script may have been made with the help of a laser. The seal reads: ‘Financial seal of the cafeteria of the Shanghai Pudong New Area Water conservancy Project Construction Management Office’ (上海市浦东新区水利工程建设管理处食堂财务专用章). This dates it to the 1990’s. Height 5.9 cm. Width and depth 2.5 cm.
