RR Auction

An auction house is selling a black and white photo of the iceberg that experts say the Titanic struck shortly before it sank on its maiden voyage.

The photo was taken April 12, 1912, two days before "the unsinkable ship" met her demise when she hit an iceberg shortly before midnight April 14, killing 1,502 people.

In Photos: Expensive Items

The photo shows a huge iceberg with a distinctive elliptical shape. The photograph was taken by the captain of the S.S. Etonian, according to RR Auction of Amherst, N.H. The caption reads, "Copyright. Blueberg taken by Captain W.F. Wood S.S. Etonian on 12/4/12 [April 12, 1912] in Lat 41° 50 N Long 49° 50 W. Titanic struck 14/4/12 [April 14, 2012] and sank in three hours."

There were no photos of the iceberg before this one emerged, but two Titanic crew members drew sketches of the iceberg that they saw April 14. Both sketches are similar to the elliptical shape of the iceberg in the photo, according to RR Auction.

The coordinates scribbled on the photograph are not far from where the wreckage of the ship lies on the bottom of the Atlantic Ocean.

"In my professional judgment, this iceberg is the one that sunk the Titanic," Titanic artifact collector Stanley Lehrer told the Daily Mail.

Lehrer is noted for his collections of rare Titanic artifacts that have been displayed around the world.

"The captain took the pictures because he was fascinated with the unusual shape of the iceberg. This particular iceberg had an ellipse on the top right of the iceberg," Lehrer added.

RR Auction expects the photo graph to sell for $8,000 to $10,000 when bidding opens Dec. 13. The photo is one of more than 400 items from the Titanic that are up for bidding.
