I grew up in the '70s and volunteered at the local recycling center, so I had a collection of literally every porn magazine from back then - Playboy, Penthouse, Hustler, Oui etc. etc. Multiple copies of each issue. Even weird high-quality stuff that showed actual penetration and cumshots and whatnot (big no-nos with the major publications at the time). Not a single bare bush in all of that stuff.
