This is a mug shaped like the stone head lair from the Island of Collasa in the 7th Voyage of Sinbad. The 7th Voyage of Sinbad is a 1958 Technicolor heroic fantasy adventure film from Columbia Pictures. This was the first of three Sinbad feature films from Columbia, the much later two being The Golden Voyage of Sinbad (1973) and Sinbad and the Eye of the Tiger (1977). All three Sinbad films were conceptualized by Ray Harryhausen who used a full color widescreen stop-motion animation technique he created called Dynamation.
