A rowdy band of bloodsuckers, gunslingers, wily wise guys, jaded private eyes, hardboiled reporters and good girls gone bad, stuck in an attic together for 80 years, is going its separate ways.

Nearly three dozen movie theater posters from the Golden Age of Hollywood found in a Pennsylvania attic are expected to fetch $250,000 at auction in Texas this month.
