Take a walk on the dangerous side of the street with these pulp covers from artist Frank Cozzarelli. I could not find much biographical information on Cozzarelli but all of the work of his that I was able to find was from the 1950s. As you can tell from the examples below, his covers were lively and detailed and included everything that we associate with the pulp era: tough guys, beautiful women, and danger around every corner!
My favorites are the covers for Murder! and Manhunt.
