Nice save. Those look like some nice family photos, its a shame they were lost or thrown out by the family. If there are any names on them, it could give you an idea of who they are. A lot of people are looking for old family photos, especially originals, on places like Ancestry.com and so forth. They could be valuable if returned to the right person. I know I would pay good money for old original photos of my family.
You should have gave warning on the last two pictures. Risque photos included. LOL
