The good old Science Fiction Book Club! Man, how I loved those Burroughs books. I still have them in my bedroom bookcase. They were part of my first shipment from the club; I still remember taking them out of the cardboard box when they finally arrived. They seemed so big to me then. I had chosen them on the order form because (how else!) I liked the covers. Mark, your posts often stir up a strong nostalgia in me.
