These might have perfectly good explanations but but uh, yeah, you go for it. If you haven't already seen these, you have now.
First clip is from a 1928 Charlie Chaplin movie extras clip. Some say she's holding up an ear horn (for hearing impaired) to her ear but that doesn't explain who's she's talking to!
Second clip is from 1938. One of the stories floating around on the interwebs says this woman's great grandchild claims the woman in the video was testing wireless phone tech. for the company she worked for. However, if you search, apparently the first sign of wireless phone tech. wasn't until about 33 or so years later . . .
The last clip is from 1995, Tyson vs McNeely. Scuttle online says it's either a time traveling smart phone or it's "just one of those hand held video cameras of the time", whatever that is. I wasn't able to find anything that looks quite like that when searching camera tech of the '90s era.
I've cropped some and slowed the footage some so you can get a better look.
Yeah, you decide on this. I'm just passing the weirdness along : )
