The set-up shots by two young women went around the world.
This month marks the centenary of the Cottingley Fairies hoax- a prank by two West Yorkshire girls that spread round the world.
They took photos of themselves posing with cut out fairies in Cottingley in 1917 and many believed they were real.
It was only years later in their 80's they admitted it had been a set-up.
Michael Terwey is from the Science and Media museum in Bradford, which is hosting the cameras used.
He says "It was a really big thing- there was an article written by Sir Arthur Conan Doyle- the writer of Sherlock Holmes and he believed they were real- it went all round the world."
