Ever wonder what it costs to rent a booth and sell antiques and art at a major show? A list recently posted on Blouin Artinfo's website reports that a booth at Art Basel costs $58,000. Then the dealers must spend money for lighting the booth and decorating it, shipping the art, their airfare, hotel and food bills, local car rental or taxis, and other minor expenses while at the show. It comes to well over $100,000. No wonder the art is so expensive at large, major shows, but dealers keep returning. That means they earned expenses-plus from sales.
