- The Red Cross [Dr. Peter Hall] (introduction, origin)
According to Peter Arndt in Alter Ego (TwoMorrows, 1999 series) #134 (July 2015), it's possible that Brodsky scripted and inked the story over Nicholas' pencils, or Nicholas did rough layouts with Brodsky finishing. It does seem likely, though, given the shared by-line and Sol's 1960s claim that he created the character, that Brodsky did more than just ink this story.
Actual credit reads: Art and Ed. originated by Charles Nicholas and Sol Brodsky
