Sheffer had a lot of valuable advice for young artists who are seeking to cultivate contacts with dealers (hint: network like crazy but don't be too pushy). There were also some interesting questions from the New York Academy students, particularly on the economics of art exhibits.
Shaffer has a wonderfully engaging personality with lots of anecdotes about both struggling and famous artists. This 75 minute video was a pleasure to watch. It's essential viewing for anyone who is curious about the scene behind the gallery scene, and how dealers go about choosing contemporary works that could possibly change the course of art history.
