Gold Key published sixty-one Star Trek comic books between July 1967 and March 1979. (Note that four of the sixty-one were actually reprints of early issues, so really there were only fifty-seven unique comics from Gold Key). I picked up a few issues at a convention in the mid 80s. They won't win a Pulitzer, but they sure are a lot of fun to look at!
Below I've included shots of the cover, the first page, and a representative sample page from each.
Issue #29 dated March 1975. This is actually the first of Gold Key's reprint issues, and in fact this is a reprint of issue #1! This issue marks the only appearance by Janice Rand. Each book has plenty of action panels.
Issue #32 dated August 1975. Some of the character work is actually pretty good, for example the Spock in this issue.
Issue #41 dated November 1976. Scotty gets a bit of action in this book. Couldn't resist including a shot of the back cover. Awesome! I picked up this issue on either July 15th or 16th 1983 at the Maplecon 5 convention in Ottawa.
Issue #53 dated July 1978. More monsters! More action!
On 23 December 1983 I opened up my first wave of Christmas presents (we would usually open up a few at home before making the trek to relatives in Lindsay and Barrie) and was happily surprised to find two of the Gold Key comic omnibus editions. These were published back in 1977 so I'm not quite sure where my Mom picked them up.
Collection #3 includes issues 18 through 26 inclusive, plus a few pages of original material, a "psycho-file" for Spock.
Collection #4 includes issues 27 through 38 inclusive, but omits issues 29, 35 and 37 which were reprints of early issues already collected in earlier collections. (Did that make sense?) Again there is a bit of new material, this time a history of interstellar travel.
Captured below are a few representative panels from the two collections.
