Perhaps she really is a time-traveller, sent back through the decades to make a jaw-dropping cameo appearance.
Or maybe she was a maverick genius, secretly testing out advanced technology for the government and caught on camera at the wrong moment.
Whatever the explanation, this footage from a Charlie Chaplin promotional film in 1928 showing a woman apparently using a mobile phone has left viewers stumped.
Have a look and see if you can work it out !
