The pin-up girl originated in the 1930s, accompanied soldiers to war in the 1940s, mirrored the rampant consumerism of the 1950s, and was eventually reduced to a bit of kitschy fun in the 1960s. The pin-up straddles that line between commercial culture and softcore porn, but in The Great American Pin-Up Returns: The AK Collection, these pieces are considered for their artistic value. Gathered from the original calendar and magazine publishers, the collection features almost 50 paintings by Gil Elvgren, Alberto Vargas, Rolf Armstrong, and other major names in the biz. If you’re looking to prolong your Mad Men high, or just a badass rockabilly chick on the hunt for fashion inspiration, browse these works and take a cue from pin-ups both well recognized and rare.
