The source for writer and art comes from Arthur Jean Cox's The Cosmic Reporter column in Fantasy Times #127 (1951-04-01). He says of A E van Vogt - "van Vogt .. once wrote the continuity for "Tigar Man" <sic> which appeared in SUPER-MAGICIAN COMICS ... Strip was illustrated by fan, Lou Goldstone" and "he had the character strip before taking the pill and becoming transformed." This is that story based on description. Vogt is here using his wife's name, Edna Mayne Hull, for the credit.
