Livescience.com has an article today that reports there is some doubt about the iceberg photograph up for auction is the one that collided with Titanic.
“There are two photos of icebergs from the area on the day following the collision, both of which purport to be the Titanic iceberg,” said Grant Bigg, an environmental scientist at the University of Sheffield in England.”
Bigg found there was another iceberg photo taken by Captain William George Squares de Carteret of the SS Minia. And believes it matches the dimensions that survivors gave of it. But there is no definitive proof that it is either.
