A Funny Bookstore Anecdote from a 1950s Science Fiction Fanzine. (Might even be true!)

A certain New York fan and mag dealer catered to the well known fannish taste for future art (commonly known as pornography) and had a code.  You ordered “fantasy mags”, “weird mags” or “stf mags” depending on whether you wanted dirty comic books, obscene photos or smutty stories.  Fans being the slans they are, he did quite well–up to the time his place was raided!  At least one Michigan fan was visited by the postal authorities, who wanted to know why they found a lot of his orders for “stf mags” etc in the dealer’s store when they raided it.
