The "time travel" video from 1928 below uploaded by filmmaker George Clarke (See His Video) from behind-the-scenes DVD footage from Charlie Chaplin's The Circus is causing a stir on the Internet. In the clip a person is seen "talking" to what appears to be a cell phone. Another idea is that the object in question wasn't a phone but in fact a hearing aid (see last video) that was available during that time (Siemens Hearing Instruments or a Western Electric Model 34A "Audiphone" Carbon Hearing Aid). But why is the person's mouth moving during the closeup (picture)? Hmm.
This person is wearing a dress.
