From Walt Simonson's Facebook albums:
"Very early Archangel design drawing. Maybe the earliest."
"It's the original color sketch done to show the colorist what I had in mind for the character's costume and look. The drawing was done with felt tip and magic marker on typewriter paper. I modified the red slashing in Archangel's final design somewhat, but stayed with the color itself in the final scheme."
"A more finished Archangel design. Pretty much done I think. The yellow color is really an artifact of Photoshop. The original, again on typewriter paper, is just pencil on white paper. But age and Photoshop combined to make it look a bit like a Leonardo da Vinci drawing. (I wish!) Ah, that Leonardo. Really ahead of his time!"
