I just came across this amazing Flickr pool of found stripper Polaroids from the late 60s and 70s. My apologies if any of these photos force you to confront your mother's previously unknown career path.
UPDATE: Turns out some (all?) of these women are not strippers. One contacted me and asked me to remove her likeness, which I was more than happy to do. Hope the owner of the Flickr pool will do the same.
