Illusion!!!

Back in the 1920's they didn't have cell phones. People had to use their house phones because they don't have cell phones but in this video I saw a women was walking down the street. What was weird is that she was holding something up to her ear and was talking to it. At first I just thought it was a cell phone but when I figured out that they didn't have cell phones back then I got confused. I thought about it and came to my conclusion that someone had to edit the video to make it look like that. There was no way that she would have service either. It's funny how only one person would have a cell phone.
