This is a nice vintage early-1970's GAF View-Master Gift Pak.  The original canister packaging contains the view master viewer and the "It's Fun, Charlie Brown" 7-reel set that features Snoopy and the Red Baron, Charlie Brown's Summer Fun and the Peanut characters. In addition, this lot includes complete, 3-reel sets for Batman, The Flintstones, Lassie, Gunsmoke, and the New Zoo Revue (no cover envelop).  The fronts of the set covers are included as pictured--the backs are not intact.  Overall--a great vintage collection.
