Gonzales credit from Julius Schwartz's editorial records, provided by DC Comics. Robin Snyder notes on the GCD mailing list in 2009 that Gonzales told him to have worked on the cover and the story. The owner of page 31 of Job Number S-5054 notes that on the back of the page in the bottom right corner, in pencil, someone wrote: "Ernie Chua (P)", and underneath: "Vince Colleta (I)".
