Notes: "Sheena, Queen of the Jungle" stories published by Fiction House from 1938 to 1953 show "by W. Morgan Thomas" on the splash page. The Wikipedia article for "Sheena, Queen of the Jungle" states that W. Morgan Thomas was a pseudonym created by Will Eisner and Jerry Iger for that character's stories. The cited source for this statement is Michael Schumacher's book Will Eisner: A Dreamer's Life in Comics (2010).
It is generally not known who actually wrote the various stories credited to this name. Actual artists have been identified for many of the stories.
The pseudonym was also used for Eisner's "Mr. Mystic" stories included in "The Spirit" newpaper section 1940-1941.
