The 1974 (75) Film Strip Catalog
Possibly the most common of the film strips as it was placed in every Apes Treehouse playset released as well as carded WGSH and Apes.
The 1976 MEGO mini Catalog
The less common of the "Mego Mini catalogs" the 1976 edition features rare shots of the prototype Comic Action Heroes and Sonny & Cher. It seems like these are almost transitional pieces for Mego, highlighting product that's about to come out. (all scans courtesy of Bill (WRM))
