This is an image from a portfolio of prints published in 2001 by Jean (Moebius) Giraud.
Dreamlike, inventive and striking, it’s yet another wonderful example of his line and color approach, without the spotted blacks and feathering characteristic of American comics art.
Note the subtle gradations in the face and headdress.
