Sweet Daddy Tiki has taken some beautiful photographs of his collection of vintage Hawaiian souvenir glasses, including this stunning tumbler from the Trader Vic’s in the International Marketplace in Waikiki. This is glass #3 in a series of six, depicting a “mating ritual” — as you can imagine, it gets a little risque. There’s a number of great glasses in the collection (Don Ho and Al Harrington are naturally well-represented).
