This is one I have thought about for a while and when I heard about Teri Garr's passing, I figured I would continue in earnest. Star Trek's second season ended with a "backdoor pilot" for a possible series that could have been America's answer to Doctor Who. While travelling back to 1968, the crew of the Enterprise meet an enigmatic character named Gary Seven. The episode is mostly about him and is actually an origin story for a possible series. The episode even ends with Spock saying that "Mr. Seven and Miss Lincoln (Garr's character) have some interesting experiences in store." It was not, however, picked up as a series so I imagined a DVD cover if the series was made and added some ideas of what stories be used. I also figure Gold Key would do a comic of it so I created an imaginary 1960s comic cover as well. Here is fan made opening credits for the series that doesn't exist, to give you an idea: Assignment Earth Opening (Improved)
