in the pics from my late sister I found Mom's graduation with about a dozen more graduates, posed, holding diplomas. I shared in her hometown FB group with the names from the back...very faded. Several people were thrilled. Their mom, Aunt, GMA, in a never seen before pic It was lovely to make so many happy so easily.
So, I've been scanning and uploading old family pictures and old local pics like the 1939 local baseball team, etc. I found I have some pictures of my in-laws family and scanned them, too, from the 40s.
