Time Travelers In 1928 & 1938 The Camera Has Caught Someone Talking On A Phone

A large woman dressed in black with a hat hiding most of her face, with what can only be described as a mobile phone device - talking as she walks alone.

I have studied this film for over a year now - showing it to over 100 people and at a film festival, yet no-one can give any explanation as to what she is doing.

My only theory many others - is simple... a time traveler on a mobile phone."
