Since we're talking about $4M photos, art, and all that, I'll share what I think are the most amazing photographs I have seen in terms of "art" - Genesis by Sebastião Salgado. I picked one up last year and I would kill to have his eyes in terms of how he sees and captures the world:

(Click on "See all Images (21)" link on the bottom right of the photo to see some examples)
The 9.6"x14" format and printing quality is amazing and to me, this is art - no flying spatulas, boring rivers, or blurry B&W with torn edges.
