This Technicolor lithograph from Champion Line is entitled “Practice Session.” We don’t know what the unidentified model is practicing, though. The panca pose from Ashtanga yoga? The funky worm? Whatever she’s doing she looks good. No year on this one, but figure around 1960 (actually 1953 or 1954 on the original shot, with the print coming sometime later—see below).
Update: We got an e-mail from Marcos: “I just wanted to say that the woman in your post is American model and former Playmate Diane Hunter. She was first known as Donna Hunter, and her real name is Gale Rita Morin. She appeared two times in Playboy magazine. She was first featured in the last page of the debut issue of the magazine in 1953 (the iconic Marilyn Monroe issue). She also posed as the centerfold in 1954, becoming the first Miss November ever. She is still alive and she is a wonderful woman.
