A 1983 work by Jean-Michel Basquiat sold at auction for $1.5 million this week, leading the way to a more than satisfactory $23.6 million night for the newly trendy boutique auction house of Phillips, de Pury & Company. Located in New York’s Chelsea neighborhood, Phillips has emerged as one of the city’s art hot spots of the moment, drawing a decidedly image-conscious crowd to bid on the trendiest of contemporary art.
