Found a couple more from Aug. 27, 1956. On this one, my Dad wrote, "Outside Fantasyland"
On this one my Dad wrote, "Indian Village from Tom Sawyer Island"
I think there are more from that day, but I haven't found them yet. I know there are also some slides from my first visit in 1965, but they must be in another box. I'll keep posting them as I come across them.
