the older the picture the more valuable they are:

UFO investigator Tom Carey claims to have come in to possession of pictures of an alien entity from 1947.

The infamous alien autopsy footage that appeared during the 1990s was thought by many at the time to represent conclusive evidence that not only had we been visited by entities from another world but that the US government was aware of them.

The footage inevitably turned out to be a hoax, but now more than 20 years on UFO researcher Tom Carey claims to have obtained a reel of photographs that he believes are the real deal.

Describing the images as a 'smoking gun', Carey took the photographic film to be verified by an expert at Kodak and maintains that the pictures are genuine.

"We took it to the official historian of Kodak up in Rochester, New York, and he did his due diligence on it, and he said yes, this filmstrip, the slides are from 1947," he said.

"It's original 1947 images, and it shows an alien who's been partially dissected lying in a case."

Carey's claim has been met with an understandably significant degree of skepticism and so far none of the actual images have been released for independent verification.
