OK I'm having fun with this DA thing so I've dug waaaaaaay back and found this... the first drawing of The Powerpuff Girls (then the Whoopass Girls) ever! Done in 1991, ( Gaaah 17 years ago!!) if it looks strange it's 'cause it was done on orange construction paper only 1 inch big.
Notice Bubbles' and Buttercup's colors are switched. I actually remember changing it by the second drawing.
