His last original published story was the five-page Ringo Kid tale "One Bullet Left" in "Gunsmoke Western" #53 (July 1959), and his final published comics work was the cover of "Gunsmoke Western" #55 (Nov. 1959), featuring Kid Colt and Wyatt Earp. Historian Ger Apeldoorn believes Maneely's last drawn work was published earlier: the first page of the eight-page story "The Revenge of Roaring Bear" in "Two-Gun Kid" #45 (Dec. 1958), which was completed by a different artist (Jack Davis), and bears the highest published job number (T-67) of Maneely's work.
