Series #1 is in-game character portrait art, but I'm unsure where this came from. This appears to
have been ripped from the game, but I could never clean my captures up enough. Ryu is missing from this gallery.
Series #2 is the awesome full-body character art. This is easily my favorite art of the game, perhaps the whole
series. The third series is a gallery of interesting portraits, incorporating several of the characters' backgrounds.
You'll see Eagle in Adon's photo, Poison in Sodom's, Guile in Nash's, etc.
Both of these fantastic galleries are from Jap Sai.
