The credits for the Casus Belli version of 1940 are attached. There is no attribution of a French artist (Rich Banner gets the credit). Also, the game was part of Casus Belli magazine #46 and not #36.

Have a nice weekend.

PS Oops, my bad: you're looking for the person who drew the art in the gamebox, not the mag. Sorry.
