The Rolling Stones classic tongue and lip logo was designed by graphic artist John Pasche.
I just came across this wonderful version of The Rolling Stones logo on a Portuguese blog called viiish.
Sticker created for Polyglot Institute, the school languages.
When I was a youngster, I had several bumper stickers with the logo (thanks to WRIF) and they were some of my most prized possessions.
Oh, the memories...
