She is not even nude, only topless

It might be a publicity stun of some kind because who has ever heard of that film? And she did not even appear naked she was only topless.

Who really is going to waste his time tracking down a 1975 film to get a glimpse of 13yo tits for a couple of seconds when one can simply head to subreddits with thousands of followers like flatchested18 or flatties where OnlyFans girls with AA tits post? Double A tits are far smaller than 13 tits, like totally flat tits that look like a 10yo but on an 18yo girl doing porn, in Germany and other countries it is illegal for a porn actress to dress like children or suggest they are underage but it is not their fault they are AA which is very rare, having that into account why are these people bothering about a 1975 film that shows a topless 13yo with what probably are A tits, like anybody cares, the film is part of how society was back then, all they accomplish by withdrawing it is to spread ignorance, now that an history record has been erased new generations will find it harder to understand what the past was like.
