This is a mug shaped like the shrunken head of Gilligan (or "Little Buddy" as the Skipper always called him), from the television show Gilligan's Island (1964-1967).
Little Buddy & The Skipper were sold as a matched set, designed and sculpted by Wolf, and then manufactured in Florida in ceramic by The Shrunken Monkey.
They are an homage to the classic television show, and Wolf's added twist is that he sculpted this mug set of Little Buddy & The Skipper as shrunken heads.
The mug set was a limited edition of 150. The wait list started early on but they were officially released for sale in October (1st half) and December (2nd half) 2018. They did not start shipping out until the end of February 2019.
