This is an odd thought, but doesn’t it look like Aleister Crowley is playing peekaboo in this gif?
Seriously. I think of this every time I see this picture. I imagine just before the camera snapped he had his hands in front of his face. Then he moved them out as shown and yelled: “PEEKABOO!” Doesn’t it look like that? Doesn’t it?
Things like this are probably why I’ve never been invited to join any secret mystical orders.
