This is a mug shaped like a bust of Davy Jones, the octopus-headed pirate captain character from the Pirates of the Caribbean film franchise.

He is wearing a hat and covered in barnacles and seaweed. A skull-faced Aztec coin is stuck to his coat on the reverse.

This was issued in two limited edition glaze variations of 100 each -- either gray or green. There were also Artist Proofs in assorted glaze colors.
