Series 1	Series 1a	Series 1b

There are three versions of the same gallery here.

Series 1 is official Capcom art, and this contains 2 sets for each character.

Series 1a contains GIF rips from the win status screen of the arcade version. This has each character's alternate outfit color. Just mouseover for that secondary color.

Finally, series 1b is redrawn art by Udon for Super Puzzle Fighter II Turbo HD (II X HD in Japan?). Note that these are only the alternate colors and are available in awesome high-res versions. The source of Series 1 is unknown. I ripped Series 1a and 1b was posted over at Gamespot

Also note I captured the backgrounds from this game and those images are featured on my personal pages here.
