This is a modified Moai Mug cast from a 1963 Duncan mold. It has the addition of a hand-built headpiece that serves as a shot glass (and also has a straw hole to drink through). These were first made with a rough-hewn stone texture and glazed gray with a red removable headpiece. Later versions were made in a variety of glaze combinations, some with removable headpiece and some with the headpiece built-in/fused to the top of the Moai.
