I have a whole stack of STARS and STROKE mags saved carefully in a box. I figure that they'll be worth money someday. They are not my originals (those wore out long ago when I was a horny young man).
A few years ago, Outlandish, Rochester's best gay store, had acquired a private collection of gay porn, and these mags were in pristine condition. I bought them up. I also bought a bunch of various picture magazines from the 70's and 80's. Some are Nova, Higgins, and smaller companies that are now long gone.
Eventually, I might even scan some of them ,so long as nobody sues me for copyright infringement.
