John Berkey, probably second to Syd Mead for iconic sci-fi art of the 20th century. Pretty much all of the new generation digital space art owes a lot to his loose indicative style. Berkey worked with a multi-mirror setup over his drawing surface so he could quickly see the "far read" of his work while he worked closely on detail. This appears to be a giant Martini liveried transport. Ever see a truck that big?
