The first thing your eye hits is the dog, and even then you might not believe it's a dog. It hangs in the middle of the frame, all motion and mop, a corded mass of white and grey flung sideways like a bundle of udon noodles thrown into a wind tunnel. It is clearing, or about to clear, a black-and-white striped hurdle propped on two silver stands that plant into the grass. And across the bottom, in blocky red Western letters, sits the answer to a question you didn't know you had: BECK! ODELAY.

That confusion was exactly the point. The image gives you almost nothing to hold onto: a flat washed-out field, one shaggy creature suspended over an obstacle for reasons the picture declines to explain. Was it a dog, a haystack, a joke? Beck wanted you unsure, and the picture keeps its secret.

How a found dog-show photograph, snapped nearly two decades before the album existed, ended up as the face of one of the 1990s' most celebrated records, and why it fit the music so precisely, is the better story.
