These little drawings represent each game released for the Nintendo Entertainment System back in 1988. These were created by Campbell Whyte, and some of the individual drawings are for sale on Campbell's Etsy store.
Before you look at that, look at this full image of all the game's drawings (found below the jump). It's fun to guess at each of the drawings. Most of them are pretty obvious, but some will make you think a bit. Or bust out a Wikipedia search. Some of my favorite and most played games ever are represented here. Great work, Campbell! Apparently 1989 is up next.
