I wrote about the fairly obscure fan magazine, All About Star Trek Fan Clubs (yeah, that was its official title). As I mentioned in that post, AASTFC was published in 1976-1977, ran six (I think) quarterly issues, and received national newsstand distribution.
The rather amateurish - though earnest and enthusiastic - magazine covered Star Trek fandom in all its pre-Internet/home video Seventies forms, with fannish articles on conventions, collectibles, episode trivia, pull-out posters, lots of fan art, interviews with the Trek cast (and prominent "Trekkers!"), fanzine reviews, and, as its clumsy title promised, extensive fan club listings.
It was an interesting magazine, and for a rural science fiction fan without access to conventions or fan clubs, it was a window onto a larger world of Trek (and sci-fi) fandom. Anyway, I included scans of the covers of the three issues I owned with that previous post. I've since snagged scans of the other three issue covers, and thought I'd share them here. Enjoy!
