A PHOTO of a city square has emerged online – and conspiracy theorists say it proves time travellers really do exist.
The black and white snap captures the busy New York scene, with street vendors and locals going about their daily business.
It’s said to have been taken by an American photographer in Brooklyn’s Union Square in 1936.
But eagle-eyed believers think they’ve spotted something out of the ordinary for the era.
The man in the foreground of the snap appears to be holding a device to his ear that bears an extraordinary resemblance to a mobile phone.
