People look at the ''Madre e Hijos'' (Mother and Children) by Mexican master Diego Rivera during a preview of Latin American art at Christie's Auction house in New York November 19, 2012. The 1926 painting, expected to fetch $800,000, depicts a barefoot boy standing next to his sister, who is ensconced in their mother's lap. The children show a gravitas beyond their years.
