This is Happening Hank by Peggy Ann Doll clothes. he had his own clothing line and came dress in a Ken clone swimsuit outfit with sandals. he's Groovy Girls boyfriend and he's marked Hong Kong on his back an has bendable legs. I think happening Hank came out in late 1960s or early 1970s. The Happening Hank Doll model was also used to make a Las Vegas Dealer Doll that has black hair with a pale ghostly face.
