Yesterday, at one of those semi-permanent garage sales, I found both of them, side by side in undated Fawcett Gold Medal printings. It's stuff like that that keeps me wasting time going to auctions and yard sales. This pair is shelf-worn but obviously unread. Since I can't recall reading either work, I think I'll tuck them in the camper for roadie use.
(Fifty cents each -- same price the sale guy was charging for Harlequins.)
