The new THE MIGHTY THOR #1 by Fraction and Coipel will have several variant covers, including one by Walt Simonson himself. The book goes on sale 4/27.
UPDATE: As mentioned in the comments, this art is from 1983 and originally ran as promo art for Simonson’s epic run on THOR. Hence the odd size of the art. Laura Martin recolored it. Simonson is DC exclusive so this is the only THOR cover we’re likely to see.
Pretty clever of Marvel…or sneaky.
Simonson’s run as writer/artist of Thor lasted for nearly three years, and he wrote it for another year. Although it took place nearly 30 years ago, it’s still a model of what a talented creator with vision can do for even a long-running company character when they’re given some track to run on. Alas, in these editorial-driven days, that room doesn’t really exist.
HOWEVER, see Marvel’s BIG SHOTS announcement.
