New York City's big-ticket auctions of impressionist and modern art get underway Tuesday.
Among the blue chip offerings is a still life by Vincent van Gogh painted weeks before his death.
There's also a rare sculpture by Alberto Giacometti that could set a new auction record for the artist.
Van Gogh painted "Still Life, Vase With Daisies and Poppies" it in 1890. Sotheby's predicts it could sell for $30 million to $50 million.
The auction record for van Gogh is $82.5 million.
The evening sale also features a major work by Giacometti that Sotheby's says could sell for over $100 million. "Chariot" is a 1951 bronze sculpture of an elongated goddess-like figure perched atop a wheeled chariot. The record for a Giacometti is $104.3 million.
