Well, since we're having a Foss party here we may as well have a look at that Dune Guild ship. Just an awesome piece of draughtsmanship, let alone anything else. Thank heaven Jodorowsky was there to pull Foss free from the world of publishing deadlines and limited paperback formats and give him those months of total freedom in which, to my mind, he produced his greatest work.
Jodo says Dune material influenced Star Wars. Maybe, but the second Foss image below from 1975 suggests the Nostromo may not be the only movie spacecraft Foss helped birth. Mounted upon the rear fins is a Star Destroyer hull, including the exact geometry of the aft quarter. Either great minds think alike, or Foss nicked it from Lucas - difficult to see how in 1975; presumably no one outside the film would've seen a SD till '77 - or Lucas nicked it from Foss. Wonder which...?
(oh, and that mushroom cloud has a touch of the Old Masters about it - mighty rare in fantasy art!)
