Is that second image a color guide? There's no color guide codes? Who did it?
So long ago, I have no clue (usually, if I get a shout out shortly after a post, I'll remember where I found it). I'm not able to look at the Kirby Masterworks today, but this may be the surfer image done in color and black'n white in there, so the whodunit would be Sinnott/Kirby
