A letter from Phil Cetrone notes that the story "The Man Who Mastered Magnetism" in Green Lantern 21, was drawn by Gil Kane, and inked by Joe Giella: the editor does not refute this. A letter from Bob Beck notes that the same story was written by John Broome: the editor does not refute this either. Another letter from Jack Harris notes that he sent in the idea for the cover of that same issue, and the editor states that for providing the idea, he sent Mr. Harris the original art for the cover.
