I think this one by John Schoenherr is eerie. How about you? I particularly like the little rover.Another Schoenherr, more macabre (as the cover notes) in tone.Otto Storch contributes a mystery cover.And so does Gerald GreggAnd inevitably, I’m throwing in a Powers cover.And one by Milton Luros. Why exactly does the Earthman want to stab the woman? I’ll probably never find out.#SFWApro. All rights to images remain to current holders.
