I have my suspicions, but the art style for them is almost identical to the art style featured for Majin Tuol, as well as several concept arts for Gigan. The Majin Tuol page says that the illustrations came from a Godzilla Encyclopedia from Japan. If only it were on sale somewhere, because I believe it's likely that the illustrations for Redmoon, Erabus and Hafun may have came from the same place.
