My very first direct experience with this was when I did a little horse show as a kid, and the local newspaper put in a picture that was identified as me on my horse. But it wasn’t.
To make it even more ridiculous, my horse was a chestnut, and the horse in the picture was a leopard Appaloosa. So it was a pretty obvious error.
Then I had to spend the next couple of weeks explaining to everybody who commented on it in school that it was not me in the picture, and the newspaper had made a mistake.
