 In January 1975, TSR printed a second 1,000 copies of "D&D", which took only another five or six months to sell out.Also in 1974, TSR published "Warriors of Mars", a miniatures rules book set in the fantasy world of Barsoom, originally imagined by Edgar Rice Burroughs in his series of novels about John Carter of Mars, to which Gygax paid homage in the "Preface" of the first edition of "D&D".However, Gygax and TSR published the Mars book without permission from (or payment to) the Burroughs estate, and soon after, a cease and desist order was issued, and "Warriors" was pulled from distribution.
