Mort Kunstler Men's Adventure

While he's best known for his work meticulously depicting Civil War battle scenes — and was even commissioned by the USPS to design stamps — artist Mort Künstler had a prolific early career painting covers for a grab bag of men's adventure magazines. Working under the pseudonym Martin Kay and Emmett Kaye, he began churning out two to three covers and at least two inside illustrations per month starting in the early 1950s. Each one accompanied over-the-top tales of exotic travels, harrowing escapes, and general badassery.
