I reckon this http://www.planetvideo.com.au/blog/2...5wallpaper.jpg on a black shirt, or this http://www.seibertron.com/images/new...CVR1+LoRez.jpg on a white shirt would look superb. That or anything from alex milne's deviantart http://markerguru.deviantart.com/

I reckon his pinups would look good as shirts too (see links below for a few of them)
