Cylinder beaker form vase with external flat rim. Well made. From Eastern Ridge (?) grave 748 (as is another stone jar 1977.109.75). The shape of the vessel roughly corresponds with Petrie's Sequence Date 80. Compare with Ali el-Khouli, 'Egyptian Stone Vessels Predynastic Period to Dynasty III' (Mainz, 1978) nos. 1007-1010, p. 137; and Barbara Aston, 'Ancient Egyptian Stone Vessels Materials and Forms' (Heidelberg, 1994), no. 37.
