Cell Phones in 1928?

OK, this is just downright wierd.

I'm willing to admit right up front that this could be a fake, but take a few minutes and watch this.

Filmmaker and Cinephile George Clarke has recorded a YouTube video where he plays a snippet from the DVD extras on Charlie Chaplin's "The Circus". When you view the clip, you see a woman walking by holding something that looks for all the world like a cell phone to her ear.

The clip was from the Hollywood premiere of "The Circus" in 1928.

Again-this could be a fake. This could have an innocent explanation.

But I'll be darned if I can figure out what it is.
