Time Travelers Caught On Film

A mysterious video that allegedly depicts a woman from the 1930s holding a cellphone has created yet another wave of online time travel hysteria in the last week. The video, which was originally posted on YouTube a year ago, led to a string of conspiracy theories that the footage was actually a time traveler caught on film. Mitosis and meiosis. Apr 24, 2018  Time travel SHOCK REVEAL: Woman from ‘3800 shows photo taken in the FUTURE' A SELF-TITLED time traveller has emerged from the shadows to reveal the deep dark secrets of time travel.

Here's an interesting little news item..watch the video and see what you reckon.

I'm reminded of the movie ('Timestalkers', made in 1987) with Klaus Kinski in it, (where someone discovers a musty old photographic plate with a picture of a cowboy in the old west holding a modern stainless steel revolver, and they discover time travelling bandits are at large..not a bad movie actually).
Of course, someone in the 'readers comments' has to go and use thier rational brain and come up with a perfectly logical explanation of something available in 1925 and which would fit the bill pretty well..
They mention a 'Western Electric Model 34A 'Audiphone' Carbon Hearing Aid (1900-1939)'
Here's a link and a pic:

Seeing as how it takes three 'D' cells though, it would be a fair old size..could be it though.
Good story none the less, and one which makes even a confirmed skeptic such as myself watching it and going 'WTF???'
