An Andy Warhol canvas depicting Jacqueline Kennedy, titled \"Sixteen Jackies,\" sold for $20.4 million Tuesday at Sotheby\'s in New York. The acrylic and silkscreen ink on canvas work repeatedly showing the wife of assassinated president John F. Kennedy led a solid, but unspectacular auction in a packed-to-overflowing room at Sotheby\'s. The price reached was at the low end of the pre-sale estimate. Jeff Koons\' \"Pink Panther,\" a porcelain sculpture of a topless blonde hugging the famous cartoon character, sold for $16.8 million. That was below the estimate of $20-30 million. Warhols dominated the top sales, with \"Shadow - Red\" selling for 4.8 million, far above the estimate of $700-900,000 and \"Round Jackie\" fetching $3.7 million, compared to the presale estimate of $3-4 million. Total sales for the evening of contemporary art were $128 million. Rival Christie\'s holds its own contemporary art auction on Wednesday in New York.
