Marvel Tales #136

This July 1955 Atlas anthology delivers exactly the kind of mind-bending strangeness its title promises. The cover by Sol Brodsky and Carl Burgos presents a genuinely unsettling scene: city blocks — complete with brick buildings, rooftop figures scrambling in confusion, and interior rooms visible through cutaway windows — appear to be floating and tilting at impossible angles above a recognizable urban skyline with a bridge in the distance. "The Mystery of the Blocks!" sets the tone perfectly for a collection of offbeat tales drawn by Pete Tumlinson, where the ordinary world has been turned gloriously, literally upside down.
