A painting by former US president Jimmy Carter has sold at auction for $150,000.
The artwork was the top seller at the Carter Center's auction of presidential memorabilia in Florida on February 26.
The piece of art was among 150 lots at the sale, which achieved a combined $842,000. They included one of only six extant copies of the Chicago Tribune's "Dewey Defeats Truman" edition from 1948, which achieved $47,500, and a baseball signed by Carter and three other former presidents, Gerald Ford, George W Bush and Bill Clinton.
The Carter Center, set up by the former president in partnership with Emory University, is a champion of human rights and aims to help alleviate human suffering.
All the proceeds from the auction will go towards the Carter Center's cause.
An artwork by Carter sold for $100,000 at a similar event last year and is further evidence of the popularity of presidential collectibles and artworks with investors.

An artwork by Russian Prime Minister Vladimir Putin sold for $1.1m in 2009.
Jimmy Carter was the 39th US president. He served between 1977 and 1981.
