This is a mug modeled after the original Trader Sam as seen in the Jungle Cruise ride at the Disneyland park in California, and with a shrunken head twist.
From The Shrunken Monkey:
"It's time for Sam's final trade! Our Salesman is 7.5 inches tall and holds approximately 24 fluid oz. Each handmade mug will include a recipe card with custom artwork and original cocktail (to ease the pain of losing your head). There are 6 color variants each order will be filled at random no two will be alike. Available only at TheShrunkenMonkey.com Limit 2 per person/address."
The Shrunken Monkey also created an East Coast Trader Sam to match the Sam at Disneyworld.
