This mug is made by Garnet McCulloch at his Fireworks Studio pottery in Glasgow, U.K. He calls it the 'Missionarys Downfall Big Daddy' in his 2012 tiki mugs catalogue - because it's used to serve the Missionary's Downfall cocktail at The Tiki Bar and Kitsch Inn in Glasgow. It's 7" tall and 4" wide at the base. Holds about 25oz. Looks like a cruder version of the classic Orchids R-72 moai mug. Note: there is a smaller version of this mug which looks similar but is thinner and holds about 15oz of drink.
