Saltarella, via the GCD Error Tracker (http://errors.comics.org/show_bug.cgi?id=8165), notes that the cover artwork greatly resembles the artwork in the story with the same character that is signed by Elkan.
While the only signature on the story is "Maxwell Elkan", implying he is the writer and artist, there is no historical evidence that Max Elkan ever was a writer.
Final appearance.
