A 1911 photograph of Thomas Edison holding an alkaline battery with his penned declaration about the invention's importance in transportation has sold for more than $31,000, believed to be a record for a signed Edison photo.
RR Auction of Amherst, N.H., said the photograph was sold Wednesday night in an online auction for $31,554. Its estimated value was $5,000.
"I believe time will prove that the Alkaline Storage battery will produce important changes in our present transportation systems," Edison wrote underneath the photo.
Bobby Livingston, the company's vice president of sales and marketing, said the signature, the statement's content and the photo's excellent condition accounted for the high bid.
