Nothing is known about the history of this card. However, Phil Candaro tells us that according to a 1964 book about Yugoslavia that he found at a garage sale, the Miss Serbia contest was a major event there during the 1930s. As each contestant walked across the stage, the announcer would describe what she looked look in vivid detail, include hair color, measurements, and types of curves (e.g. "melon-like" or "quarter-moon"). The contest was suspended during World War II and not brought back until 1959, as a television broadcast. Now that the audience could actually see the contestants, the popularity of the pageant declined rapidly and it was canceled in 1962.
