Spiegelman and Kidd (2001), p. 91, do not specify who wrote the uncredited story; the Grand Comics Database entry for the issue cites it as possibly written by Cole.
Spiegelman and Kidd (2001) give Cole's birth and death dates as "December 1914" and Wednesday, Aug 13, 1958; that death date also appears in Cole's suicide note to Hugh Hefner and in an Aug 14, 1958, Chicago Sun-Times news report, both reprinted in the book. The Jack Cole entry at the Lambiek Comiclopedia gives his birth date as December 14, 1914.
