This Planet of the Apes Movie Viewer came with two filmstrips.
PotA Movie Viewer notes:
Filmstrips are hi-res scans. Ok to zoom in to see individual frames.
Filmstrip #1 is excerpted from "Terror on the Planet of the Apes,"
Filmstrip #2 is excerpted from "Terror on the Planet of the Apes," pages 17-22
Both are from the Marvel Planet of the Apes magazine, No.1, August 1974.
I folded the card in fours for storage. What was I thinking?!
Also, when I got this 40+ years ago, I remember being bummed about the
filmstrips not being clips of the movie or even the TV show.
