Above, a cover for Gerald Kramer's Apartment Party, 1966, from Midwood Books. Kramer was a pseudonym used by Jerry Weil, author of books such as Nobody Dies in Paris, Naked in Paris, and The Spy Who Came Home To Die. He also wrote quite a few other sleazers for Midwood, so we'll certainly see him again. 

The hitchhiker has been a central element of many a mid-century thriller, with the results of these rides ranging from hot sex to bloody murder, and several outcomes between. Above you see a cover for Jean Holbrook's Girl on the Run, and below is a collection of more paperback covers depicting various characters casting their fates to the road. Wish them luck—they’ll need it. And thanks to all the original uploaders on these.
