For the past few months, Tor.com (publisher of fine fantasy and science fiction books) has been promoting their upcoming website redesign by releasing weekly FREE e-books by their authors, and FREE wallpapers featuring art both old and new. (Sizes range from iPhone to enormo-vision!)
This wallpaper is no longer available, so here’s a zip file of all sizes for your downloading pleasure (3.64 Mb).
About the artwork:
Jeff Jones’ cover art for Amazing Science Fiction magazine, September 1970. See more from this artist at http://www.ulster.net/~jonesart
