I, and I alone, know the answer to this mystery.
The woman in the film footage is my mother-in-law. I have made reference to my MIL being a large lady...well, to be bluntly honest, she is so large that it is impossible for all of her to fit into any one moment/place on the Space/Time Continuum. Her girth is so expotentially mind boggling that some of her body gets pushed into other points on the Space/Time Continuum. On that particular day, her fat ankles, large feet, manly hands (still clutching her cell phone) and her rather blockish and massive head were occupying Space and Time in 1928...and just happened to be recorded on film.
This is not a time traveler, simply a circumstantial filming of a portion of my gargantuan mother-in-law and the odd distortions that her super mass causes in the universe.
I hope your wife wasn't standing behind you as you typed. It would be the last we would see of you. lol
