Hammer double bill...with stamps!

A Tucson drive-in double feature the first week of May, 1965. The Gorgon has Hammer duo Christopher Lee and Peter Cushing fighting a creature who can turn people to stone. The Curse of the Mummy's Tomb is a lesser Hammer effort (see my review here).

Not sure what was going on with the "black stamps." I first assumed they were stamps like Easter seals, but they were probably inked stamps that kids could apply to their hands or faces or whatever.
