The clothing of the man in the middle of the picture is strikingly different from the surrounding persons'. Most outstanding are his radical hairstyle, sunglasses and his T-shirt, adorned with a large letter M on the front.

Although some explanations exist for the existence of this photo, none of them are particularly convincing or well-grounded. Most people dismiss the time-travel theory for the origin of this picture, one cannot easily shake the feeling once having seen it.

A: That dimension gate is sick, man. Imma have a look real quick and see what's on the other side

B: Radical, you the time travelling hipster, dude!
