The Sears artwork is quite interesting, I like the red background even though the player looks a bit slow.  If you look closely you'll see the Fuji logo on some of the players helmets, Atari did this with most of their sports games (Team Atari!).  The Atari picture has one of those odd 'spheres' in it which must have been the trademark of the artist as it's seen in numerous early Atari titles.
