Llana of GatholPaperback, 15 January 2019

The book "Llana of Gathol" first appeared as four separate stories, published in the pulp magazine Amazing Stories, comprising "The City of Mummies", "Black Pirates of Barsoom", "Yellow Men of Mars", and "Invisible Men of Mars". We present the original texts as they first appeared in print, including the mistakes made by Ray Palmer, editor of Amazing Stories, in his editing of "Invisible Men of Mars", where he added text and dialogue to match the cover painting, but then forgot about the initial changes and failed to keep the storyline constant (dealing with the helmet worn by Mortus, not found in the original story but needed because of the cover painting).
