I ama ctually nearly positive that this is not two people. it’s street art done by some dude in the states. He makes all sorts of ones. My fav is where it looks like a guy has his head in the wall.
these are manakins. You can tell because doing this with someone else would hurt a hell of alot and strain the shit outta yur legs. also look at the feet. the balls of the feet arent even on the ground. these two would have to weigh very little of that to be possible.
