But this comic was something of a bait-and-switch, because it mostly consisted of reprint war stories that did not feature Sgt. Rock. If you're expecting a full 80-page book crammed with Rock, you've got another think coming, Melvin! Though the stories are beautifully drawn tales by Joe Kubert, Ross Andru and Irv Novick, only one tale featured Rock, a 13-page story at the end ("Calling Easy Company", reprinted from Our Army at War #87). DC pulled the same trick in 1976 with Limited Collectors' Edition #C-47, "Superman Salutes the Bicentennial," which featured exactly zero tales starring Supermanthey were all reprints starring Tomahawk! At least Sgt. Rock's Prize Battle Tales #1 included this nifty black-and-white inside-back-cover pin-up poster with gorgeous artwork by Joe Kubert:
Our Army at War changed its title in 1977 to Sgt. Rock with issue #302, and DC's top combat soldier finally got a comic named after him, which ran until ish #422 in June 1988. Rock's second annual would follow in 1982, when DC resurrected their annuals after many, many years of absence. See this feature on this coming Thursday for a peek at a house ad announcing the annuals' return!
As far as I can think, there's only one other DC annual that appeared before the main character had a comic book of their own, and like this one, it didn't bear the exact title of the book that would eventually appear! That's your clue, and we'll have the answer...not tomorrow, but in this very spot on Saturday! Be here or be there, annually!
