The Art Basel art fair opens, and as much as $300 million in sales could be made. “Names on collectors’ shopping lists include classic contemporaries, such as Andy Warhol; artists in mid-career who did well at the New York auctions, including Prince and Kippenberger, and younger ones who have waiting lists for new works, such as Kai Althoff and Neo Rauch, say collectors and dealers. It’s hard to see who the promising new artists are because a rush of money into the market has pushed up prices for everyone in recent years.”
