An Abraham Lincoln supporters' banner from the 1864 US election is to cross the block at Heritage Auctions.

It's expected to make in excess of $85,000 in the May 18 sale in Dallas.

The Lincoln campaign banner was carried by supporters in 1864

Heritage comments: "No category of political campaign memorabilia is more highly prized than the 1860 and 1864 flags supporting Lincoln's candidacy.

"Such a unique artifact is very difficult to value. Other varieties of Lincoln portrait flags have been traded, publicly and privately, mostly for prices ranging from $50,000 to nearly $200,000 over the past decade."

The present lot is one of the very rarest examples, which show a portrait of Lincoln. The record for a Lincoln campaign flag stands at $83,650, set at Heritage Auctions in 2007.

A lock of Lincoln's hair is also on offer, with an opening bid of $16,000.

It was taken from his head shortly after his assassination.

Earlier this year a lock of Lincoln's hair made $25,000 at Heritage Auctions.
