Don't believe this is the same image? I didn't either and that's why I created an animated gif to prove it. The Thatcher effect is a phenomenon where it becomes difficult to detect local feature changes in an upside down face. This strange human glitch was named after Margaret Thatcher, whose image this was first tested on. These images were taken by Anuschka Blommers and Niels Schumm for the new Dove Campaign. You'll have to watch it a few times to believe it for yourself.
