Godzilla’s Revenge / War of the Gargantuas U.S. movie poster (Maron Films)

While both film titles on this double feature poster appear to be hand-lettering at first glance, the second one actually is set in a face from Photo-Lettering’s fathomless library. The bold caps that look as if they were coarsely cut from paper are from one of the lesser known designs by Ed Benguiat. It’s shown in Alphabet Thesaurus Vol. 2 (1965) as Benguiat Cinema, with many alternates. Daniel Gauthier made a digitization named IrwinAllen (GautFonts, 2004), sadly without giving credit.
