There's a random painting from 1860 called "The Expected One" by Ferdinand Georg Waldmüller that's going viral right now. And there's a good reason: It might show a time traveler.
There's a woman in the painting and it sure LOOKS like she's holding an iPhone and maybe even looking at the screen.
And sure, some people MIGHT say she's actually holding a small prayer book in her hands, but we know a phone when we see it ;)
