Charlie Chaplin Cell Phone Mystery

Take a look at this photo. Doesn't it look like this lady is holding a cell phone up to her ear? You would think so, except she's at a movie premiere for the Charlie Chaplin film The Circus. The Circus came out in 1928 - no mobile devices back then. She was recently spotted in film footage showing bystanders walking past Grauman's Chinese Theater in Hollywood, where the movie premiered. Filmmaker George Clarke, a Charlie Chaplin fan, was the first to discover the mysterious woman while watching a Chaplin DVD boxed set and posted it online searching for answers. The most common explanation being thrown around is that she is a time traveler! I'm thinking most likely she was using a hearing aid, which were pretty big and bulky way back in the day, or perhaps an early radio. Or maybe she somehow was testing an early invention. Still, it makes for some pretty cool debate so close to Halloween. 

Here's Clarke's video clip showing the person over and over again - I have to admit it is kind of creepy and fascinating to watch, especially as the person with the mobile or non-mobile device sort of fades away as the camera footage changes, and you can see her mouth moving in close-up shots. What do you think it is?
