A Gustav Klimt portrait painting sold Tuesday for $236 million, a record for a modern art piece, at an auction where a solid gold, fully functional toilet satirizing the ultrarich also fetched $12.1 million.

Klimt's “Portrait of Elisabeth Lederer" sold earlier after a 20-minute bidding war, also becoming the most expensive work of art ever sold by Sotheby’s worldwide.

The portrait was one of the few by the Austrian artist that survived World War II intact.

It depicts the young daughter of one of Klimt's patrons and was kept separate from his other paintings that were burned in a fire at an Austrian castle.

The piece was part of the collection of billionaire Leonard A. Lauder, heir to cosmetics giant The Estée Lauder Companies.

He died earlier this year.
