USA Super Street Fighter II artwork
This airbrush painting of Cammy was done by Mick McGinty, who also did the US covers of the SFII series. I found it next to an old SSFII article in a German Sega magazine.
Dee Jay and Fei-Long were scanned from Nintendo Power. Here is a compilation of all four including T. Hawk.
(thanks to Kung Fu Man for the 3 scans!)
