What's in your library?

Got any gems like theses in your stacks? I have been browsing around Half Price Books a few times in the last several months. My buddy Nick just found some good ones last week. To turn an old adage on it's head, I judge these classics of Sci-fi by thier covers. Indeed, it's probably the main reason I keep these around, and chiefly what I look for in new (to me) books of the post war sci-fi explosion. I'm 100% behind art like this, and the idea that science fiction used to be hoarded, sought out, craved, and supplied in magnificent psychedelic splendor. Cheers,
