A previous Planet of the Apes card set had been produced by Topps in 1969; but whereas that set had used photos and the storyline from the first POTA film, this set dealt with the mid-70's TV show.
The card fronts showed a large color photograph from the TV series, surrounded by a white border around the edge. The card title appeared in a red scroll-like shape superimposed over the photo. Note: the 1969 POA set featured identical card front designs.
Card backs featured a puzzle piece for the top 2/3, with the card title and a block of narration about the photo below that. The card number was at the lower left, and along the bottom ran an identificationi of the puzzle piece (i.e., 'No. 2 of puzzle D') and 'Collect all 66 cards.'
There is also a 1967 copyright date, which causes some people to either think this set was released that year, or to confuse it with the previous POTA set; but this set is easily differentiated from teh other by looking at the backs of the cards. The 1969 series had green-tinted backs with no puzzle pieces.
