The Teenage Mutant Ninja Turtles are coming out in full force at the X Games starting today, and street artist Mike Johnston is celebrating with an original poster created specifically for the event. The poster will be handed out at the Teenage Mutant Ninja Turtles experience tent, which includes other giveaways and a photo booth. Mike Johnston will even be on hand throughout the event to sign the exclusive print. The tent goes up starting today, and will be there until June 8. If you can't make it, check out this one-sheet from the Austin based painter who dabbles in murals and stencils, skateboard decks and sneakers. You may know him from his street mark: 'Truth'. He will be painting on the X Games graffiti wall live between now and Sunday.
