On my recent trip to PA, my mom gave me some old pix I shot in 1974 or 1975 with a cheapo plastic-lens camera. I think it shot 120 roll film (roughly 2 inches square), my first encounter with medium format. But the plastic lens (with fixed focus, no less) didn't really do the big frame justice.
Anyway, here's another 12-frame mosaic, this time with actual people in it. More here.
