Jeep's 75th anniversary is going swimmingly, at least in terms of the marketing. The Fiat Chrysler brand ran those two great commercials on Super Bowl 50. And now comes a fun stunt from Jeep in Germany and creative studio Parasol Island—limited-edition mud masks for city Jeeps that don't get a chance to get dirty often enough.

The Jeep Mud Masks "contain exactly what a true offroad adventurer is missing in the city: 100 percent real dirt, as an expression of the desire to escape the daily grind and search for new adventures far off the beaten track," the brand tells AdFreak.

Check out some product shots here:

The launch comes with a black-and-white film featuring brand ambassador Elyas M'Barek and the Jeep Renegade. Watch that spot here:

The Mud Masks are not for sale. Only 75 have been made, and Jeep fans must visit www.jeep.de and sign up for a chance to win one of the "exclusive adventurer beauty treatments."
