The Coexist logo is famous on bumper stickers and around the world — but it’s also at the center of quite a few battles. Vox’s Phil Edwards looked into it…

When Piotr Mlodozeniec designed the first Coexist logo, he had no idea how quickly — and how far — it would spread. His design for Museum on the Seam became iconic, and it was also closely copied by a designer t-shirt company, worn by U2s Bono on stage, and aped by hippie bumper sticker makers — all without his permission. This is how it happened and what the Coexist logo really means.
