Sotheby's auction house has a rare photo of "Old Broadway" believed to be photographed in 1848 for sale for a cool $50k-70k. The significance of this is that very few photos were taken of the once countryside of upper Manhattan, the photographers mostly focused on the vibrant lower Manhattan area. "It is one of the earliest known photographs of New York City that we know of," says Denise Bethel, a Sotheby's vice president and its curator of photographs. The only way that Sotheby's knows that this is of New York is that one photo is identified with "the main road... called a continuation of Broadway." It was a term used back then for the Bloomingdale Road, constructed in 1703 which along with the Boston Road, now Park Avenue, was one of the main North-South arteries into Manhattan. Bloomingdale or in the original Dutch, Bloemendale, was the Upper West Side. A note was attached to the photo with information about when and where it was taken.
Daguerreotype was the method used to capture this picture on the 4 1/2 by 5 1/2 copper half-plate. This process was patented by Louis-Jacques-Mande Daguerre in 1839. It was originally used for portraitures but later when the process matured it was used for outdoor photos.
