People look at a 1939 Alfa Romeo 8C 2900B Lungo Touring Spider displayed at Sotheby's in New York City, New York, U.S. July 21, 2016. The car, unveiled in a pre-publicity showing in New York on Thursday, is expected to sell for more than US$15 million – and could set a record for the most money ever paid for a pre-war auto at auction.
