A printed copy of the Emancipation Proclamation signed by Abraham Lincoln will be auctioned in New York City. Robert F. Kennedy later bought it.
The 1863 document that declared all slaves "forever free" hung in Kennedy's Virginia home for four decades, the Associated Press reported. His widow, Ethel Kennedy, is selling it at Sotheby's auction house on Dec. 10.
The document is estimated to bring up to $1.5 million. It's one of 48 printed copies Lincoln signed. About half are known to still exist, according to Sotheby's.
The original, handwritten proclamation is in the National Archives.
