The story, of course, could not know or take into account the future Shazam! (DC, 1973 series) #1 (February 1973) story in which the entire Marvel family and friends are tossed into Suspendium for 20 years. Therefore, it would have made Freddy biologically only 95 years old for this story.

Original indexer listed artist for this story as Mac Raboy. Art-spotter Kelly Izaj thinks the artist on this story was Al Carreno, reporting during July 2008. Dennis Summers reported to the GCD on April 25, 2020 that he too is convinced this is not Raboy's work, but he is uncertain who it might be.
