Art credits from Richard Richmond, via the GCD Error Tracker (http://errors.comics.org/show_bug.cgi?id=6278); previously (December 17, 2003) Ken Webber has suggested the possibility that the art was by George Wilson. Richmond notes that this is one of six Gollub paintings identified and represented with a photograph of the original painting appearing in Edgar Rice Burroughs Library of Illustration Vol. 2. In the photograph the painting is actually signed by the artist. The signature was outside the portion used for the actual cover.
