Sotheby's hammered down 50 lots of contemporary art for $190 million Wednesday night with an excellent 94.3 percent sell-through rate. Five artist records were broken.

Minimalist paintings made a big splash. Richard Serra’s “Corner Prop” sold with one bid: $1.98 million.

Andy Warhol's "Self-Portrait" reached $32.56 million. Bidders then clamored for Mark Rothko’s “Untitled,” a 1961 red-hued canvas, which went to $31.44 million.
