UFO expert Tom Carey claims to have been given the images by an agent from a US intelligence agent who operated during the Second World War.
A UFO researcher claims to have been given an authentic image of an alien, supposedly taken after an autopsy in the top-secret Area 51.
The photo, taken on film, was sent to Tom Carey and has been verified to date back to 1947 by Kodak, the same year of the infamous Roswell ‘crash’ in New Mexico.
Mr Carey has now contacted Kodak historians to seek further confirmation on the date the image was taken.
He said: “‘What’s interesting is, the film is dated 1947.
“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.
“It’s 1947 stock.
“And from the emulsions on the image, it’s not something that’s been Photoshopped like today.
“It’s original 1947 images, and it shows an alien who’s been partially dissected lying in a case.”
Carey believes that the creatures are four feet tall, and added: “The head is almost insect-like.
“The head has been severed, and there’s been a partial autopsy; the innards have been removed, and we believe the cadaver has been embalmed, at least at the time this picture was taken.”
But not all are convinced by the photo.
Nigel Watson, author of the Haynes UFO Investigations Manual, said: “Usually when people make promises that they have the smoking gun of ufology – positive evidence of their existence – they come to nothing or they produce rather underwhelming evidence.
“However, if aliens were retrieved it would be a world changing event and I can’t imagine they could keep the lid on such an event throughout the 50s and 60s.”
