Time Traveler Caught on Charlie Chaplin Film from 1928?

This is film captured from the 1928 film "The Circus". Looks as if a woman is walking by talking on her cell phone. If you're going to go to the trouble to dress for the time, try not to walk down the street talking on your iPhone looking like a Looney Toon. Maybe it was common back then for people to walk around talking to their hand. Wonder if she had any cool aps on her hand?
