This is an artist proof of the Skull mug that Bosko made for False Idol. The mug is shaped like a large skull and was designed and manufactured by Bosko. It has large eye sockets and is missing its lower jaw. This mug is based on Bosko's own carvings at False Idol. Bosko also made a yellow first edition False Idol Skull mug and followed up with a second edition green & red holiday edition Skull mug.
