Talk:World Game (novel)

Does anyone know what's up with the two different covers for this novel? My copy has a much more austere-looking Troughton with more soldiers in the background (not the one currently posted here). I can't find any reference anywhere as to why there are two images. Were they both published or was one a draft? Birchl ☎  00:50, February 12, 2013 (UTC)
