The Opel Blitz 'Strassenzepp Essen' was a German bus from the mid-1930s. It was built by the truck body workshop of Ludewig Brothers on the chassis of the well-known Opel Blitz 3-ton truck. The bus featured an unusually futuristic exterior for that time and was extensively used in promotional activities to demonstrate the progress of Germany's motor industry. Overall production of this type was limited. However, completed vehicles were used not only for propaganda but also for transporting excursions around cities and for foreign guests during the 1936 Olympics. Some of the 'Strassenzepp Essen' buses were later passed on to Luftwaffe military departments for crew transport.
