Here is an example of a good poster for a very bad movie. The 1976 joint UK/Greek production Land of the minotaur was a complete disaster and it’s terribly dull. Even Peter Cushing couldn’t save it. This one sheet cost me about $7 probably 12 years ago. Some doofus put pin holes around the minotaur’s head and there is cracking around the creases, but still worth what I paid for it.
