On a recent travel adventure, I happened to wander into a "Recycle Store", a business which tries to take one person's junk and turn into someone else's treasure.
This store happened to have a huge barrelful of old, discarded slides and photo negatives. Turns out that most of these discarded pictures were of sporting events. Probably 95% of them were pictures of NCAA and NFL football games, but there were some baseball pictures in the pile, too.
So I gathered up as many baseball pictures as I could find, and bought a couple handfuls of the old photos.
None of these photos were marked in any way, so there's the game: let's try to identify who the people are in the photos, and figure out where and when the photo was taken.
