On the occasion of the release of the Superman postage stamp, the USPS released an entire reprint of Action Comics #1. The reprint had an additional outer cover (half-sized) that carried an example of the stamp with a first day of issue endorsement. Originally issued sealed in a clear wrapper.
In Alter Ego #56 (Feb. 2006), in an interview with Adler, he reports that he painted the colors on the engraving plates for this story. Info added by Craig Delich (Feb. 2006).
Error Report #2990 by Mike DeLisa states the following: "Cover was not by Shuster, actually by unknown member of DC staff based on one interior panel. Coloring was not by Jack Adler; Adler states that the work was done by DC staff. My source is the Court record and decision, which includes affidavits from Siegel, Shuster, and Adler."
Superman/Batman #41 indentifies bystander on cover as Rick Radomski of Radomski Hardware. Though this takes place during a dream sequence, the name could be considered canon.
