Comic Book Cats, number 133: Kona, Monarch of Monster Isle #5, drawn by Sam Glanzman, written by Don Segall and lettered by Charlotte Jetter, published by Dell Comics in January 1963.
A denizen of one of those mysterious lost islands in the South Pacific inhabited by cavemen, dinosaurs, giant animals, and other fantastical menaces, the prehistoric Kona made his debut in Four Color #1256. Following that he starred in his own series which lasted for 20 issues (confusingly numbered from #2 to #21). The highlight of the short-lived Kona, Monarch of Monster Isle was definitely the stunning, detailed artwork by Sam Glanzman.
Issue #5 featured a gigantic cat. The titanic tabby is revealed to be Amsat, a previously-ordinary cat kept as a mouser on a U.S. Navy ship. Accidentally left behind on an island where the military was testing nuclear bombs, Amsat grew to giant size, eventually tussling with the sharks in the waters around his island home.
Amsat is obviously intended to be a dangerous animal, but Glanzman draws him just so cute and adorable that when “the Monster Cat” is finally defeated and killed I couldn’t help but feel sorry for him.
Sam Glanzman is best known for the numerous war comic books he drew during the Silver and Bronze Ages. Among these were a series of autobiographical war stories about his service aboard the U.S.S. Stevens during World War II. Glanzman also worked in the horror and Western genres. Kona, Monarch of Monster Isle enabled him to try his hand at “lost world” adventure-type stories, and he did some good work on the title.
