Looking up stuff re the horror film The Gorgon (1964), I found this pressbook supplement for that film & The Curse of the Mummy’s Tomb .

My guess would be Black Stamps were some kind of loyalty program, where cinema patrons could exchange the stamps for something.

  • Were the stamps only for horror films from Columbia?
  • What are some examples of things you could get in exchange for Black Stamps?
  • What was the Columbia Exchange (bottom of page 2)? A physical store, chain of stores? Mail order? Something else?

    And thanks also for explaining film exchanges. I wonder when they died out, the Wikpedia article makes it sound like it was long, long before the digital era.
