Been meaning to pick this up for several years now, and finally found a decent copy at the right price:
Moskowitz, Sam. The Immortal Storm. The Atlanta Science Fiction Organization Press, 1954. First hardback edition, a very good+ copy with slight rubbing to spine ends, slight bump at top rear board, and slight crimping at head and heel, in very good dust jacket with shallow chipping at head, heel and top front, and slight age-darkening to white areas. His acclaimed book on the early history of science fiction fandom. This is the first hardback edition, having been preceded by a mimeographed edition. Currey (1978), page 380. Chalker/Ownings (1991), page 51. Interestingly, Currey and Chalker/Ownings disagree on the print run, with Currey citing 1000 copies printed, but Chalker/Owings saying only 500. Bought for $36 off a major SF book dealer.
