I noted several authors...lots of Burroughs, deCamp, Moorcock, and Norton, but also a bit of Fox and others. Some of the specific titles were also on the shelves - The Fallible Fiend, The Compleat Enchanter, The Carnelian Cube, Lest Darkness Fall, and The Broken Land.
Possibly worth a look.
Even with my extensive collection, I was able to pick up four volumes that (I believe) were heretofore missing from my shelves.
