The image you see above is the first known UFO image ever taken. It was taken during the winter of 1870 close to Mt. Washington in New Hampshire by an unknown photograph. The image shows what looks to be a cigar shaped UFO, the most common UFO shape of those days and it is actually a stereo image, or in other words 3D.
The original image was up on EBay 2002 and was sold at a price of $385 to one Samuel M. Sherman, who was the president of Independent-International Pictures Corp. Samuel have also stated that the image would not be locked in some collection, but will be available to scientists who wants to study it.
