I've been to Bruce Silverstein's photography gallery in Chelsea several times, but I've never met Silverstein himself. So I found this article in the Wall Street Journal particularly satisfying. It's always enjoyable reading about financial wizards who couldn't find happiness on Wall Street and turned to art as a second career. For the rich, beaten-down lawyers and traders who read the Journal, this is wish-fulfillment at a high level. Silverstein also offers a business tip that any dealer (or struggling artist) would do well to keep in mind: Know your product, know your clients, and don't be afraid to push a broom yourself.
