Iron Man by KMNDZ

In 2008, Gallery 1998 in LA hosted the "Stan Lee Tribute Art" exhibit, where a bunch of non-comics artists did Stan-inspired work. The art was really great (I have a pdf capture of the whole exhibit) and if I had had $50,000 to spend I would have picked up as much of this art as possible. I had to make A choice, so I nabbed this terrific Iron Man piece. It is huge: 20x50 on two wood panels, inside the larger frame.

Google search on "Thor" by Yoskay Yamamoto for my second favorite piece in this exhibit.
And the close runner-up: "Super Sentinel" by Max Grundy
Also: "Fantastic Four" by Johnny Yanok & "Invisible Girl" by Chris Reccardi

I'd post the pdf of exhibit if I could.
