Vintage Planned Parenthood issue of Spider-Man comicSpiderman fan Andrew Farago was browsing in a favorite bookstore in the world, San Francisco's KAYO Books, when he stumbled upon a Planned Parenthood issue of The Amazing Spider-Man from the 1970s. Actually, the title page reads "Stan Lee presents: A Special Planet Parenthood Issue Of The Amazing Spider-Man" and it was distributed by Planned Parenthood Federation of America. The inside cover contains ads for Planned Parenthood booklets and the back pages include "the facts" about pregnancy, VD, homosexuality, etc. Thankfully, Andrew scanned and posted the whole comic.
