Comic Book Cats, number 176: Superman newspaper comic strip drawn by Wayne Boring and written by Alvin Schwartz, published on October 14, 1956.
After an encounter with “a runaway comet loaded with deadly radiation” Superman somehow begins gaining weight, and no matter what he does he’s unable to shed those unwanted pounds. In order to rescue a cat that has fallen down an old cistern, the Man of Steel has to dig a hole down parallel to it, because he’s now too fat to just fly down the well and scoop up the poor kitty!
Wayne Boring began working on Superman and Action Comics in the early 1940s, and he also regularly drew World’s Finest Comics. He was primary Superman artist during the 1950s and also worked on the newspaper strips. By the 1960s Curt Swan had succeeded him as the main Superman artist, although Boring still occasionally drew the character. Unfortunately he was one of the veteran creators fired by DC Comics in 1967 after they had requested health & retirement benefits. During the 1970s Boring did some work on comic strips and penciled a handful of stories for Marvel Comics. He briefly returned to DC in the mid 1980s, drawing Superman and All-Star Squadron. Boring passed away in February 1987 at the age of 81.
