The artmarketblog.com has been writing articles for a while now on the deceptive practice among the leading auction houses, of staging a "contemporary art" auction. What they do is, put a few Warhols up, then a bunch of unknown artists, since they are all part of the same auction, people think they are buying something valuable.
In the picture for this post you can see a grab of David Kassan's DVD sales page. The reason it is there, is if you really want to be the best, you should know how to draw. I suggest buying this DVD and anything from David Kassan, Jeremy Lipking or Tony Pro. If you want to learn, why not learn form the best?
