What threw me was the "bottom row" part. Different monitor resolution settings mean posts format with different numbers of columns and rows of pictures for various people.
As for Rain Pryor, I have no idea. The date and location labeling on the pictures Life has just made available to the public are lacking, to put it politely. As I said in the original post, all of these were listed under Raquel Welch. What's worse is that in this case, the only other information on any of them is "1984" or "1981-1983", which even I can tell is flat out wrong for many if not most of these.
