Details: The poster is of Clock Explosion, by Salvador Dali. It shows the well-known depiction of a melting timepiece. The clock, or pocket watch, is both melting and exploding over the edge of a brown cube that sits in an odd special dimension. A cloudy blue sky is in the background as the pieces of the watch fly off into the blue yonder.
