Lots old memories here!
I definitely remember that Swank issue with the women wearing the same dress. Up to that time I always thought Swank was a little too "sophisticated" (for lack of a better word) for anything like that, but I was pleasantly surprised. I always got the Cavalier and Nugget magazines for their articles and letters from readers describing their fights.
The more "exotic" magazines described here, like Claws, Amazons In Action, and Fighting Gals Monthly weren't on the newsstands that I knew about, rather they could be found at adult bookstores, along with some x-rated girl fight magazines.
