1950s Mercedes dealer sign. This large painted porcelain style metal sign adorned a Mercedes-Benz dealership in the 1950s. It measures 39.5″ in diameter and was made in period by ‘S.A.S.A.G.O.’. The sign is in lovely overall condition but with some smaller minor wear to the edges and faint scratches to the main body. We can’t think of a cooler sign to hang in your garage or dealership over your Mercedes 300SL Gullwing or Roadster!
