Slides
Slides are the coolest things. It's a photo on film in a cardboard holder. Put it in a projector and with the lights turned down, you drift into another place and time. On a recent antique/thrifting trip in New Braunfels, Texas, I happened upon five sets of Fort Davis National Historic Site slides that were intended as souvenirs. Sold in the little gift shop, you could recapture that feeling of the fort in the days of the old west.
