About Fantasy Masterpieces (1966)
Marvel sought to capitalize on the popularity of their then-current books by presenting a series of anthology titles whose focus would be reprinted early material. Thus was born a series of titles: Marvel Tales, Marvel Super-Heroes, Fantasy Masterpieces, and Marvel Collectors' Item Classics. Square-bound, with $0.25 cover prices (as opposed to the $0.12 regular books), these editions would be 68 pages, and include a variety of interior features. Eventually these titles would reduce in page count and focus on individual features, and other reprint titles would spring up to support the displaced features. These titles included Marvel Spectacular, Marvel Double Feature, Marvel Triple Feature, Marvel's Greatest Comics, and others.
Fantasy Masterpieces (1966) initially focused on reprints of Atlas-vintage monster and supernatural stories, but later included Golden Age super-hero stories in the mix. Stories were culled from titles such as Strange Tales, Journey into Mystery, Tales to Astonish, Tales of Suspense, Amazing Fantasy, and others.
Although always distributed under the Marvel Comics Group imprint, the Publisher of record in the indicia was Zenith. This was a vestige of the transition from Martin Goodman's ownership as the modern-day Marvel Comics arose from its Golden Age roots in Timely / Atlas.
