Trove from Churchill's daughter up for auction

Sotheby's auction house is selling art, books, furniture and a humidor owned by a well-known Briton who traveled the world on high-level diplomatic missions during World War II, met Roosevelt and Stalin and loved a good cigar.

No, it's not wartime leader Winston Churchill but his daughter, Mary Soames.

The auction of her artworks and artifacts on Wednesday offers an unusually personal look at her father and a pivotal moment in history.
