Preamble: the youtube clip that I’m posting today involves artworks that get priced at millions of dollars. I thought it was a really cool (albeit cynical) summary of how artwork pricing works. I’m also going to link to two longer posts, which I hope you’ll check out. I am less cynical about the art world – but perhaps that’s just me.

Here are those two posts where I actually wrote something:

• African Contemporary Art: The Investment Case
• How Art Gets Its Value
