The loudest little logo in rock history: a wet red tongue lolling between two fat scarlet lips, thick black keyline, nothing else. John Pasche drew it for Mick Jagger in 1970, and it hit the world on the inner sleeve of Sticky Fingers in 1971. It has never once looked dated.

The whole system runs on that one gesture — an obscene, grinning splash of vermilion floated on hard white or slammed onto black, oversized until it's rude, cropped until it's a pattern. Flat pop-art swagger with a lick of anti-establishment sneer: no gradients, no gloss, just confident ink doing all the shouting.
