This is a well-known livery from the 74 and 75 years in German motor racing.
Tebernum was one of the top teams in DRM and European GT, competing with Kremer, Gelo and Max Moritz. Their main driver was Clemenz Schickentanz, who had won the European GT series in 1973.
This livery is based on the car of the Zolder Trophy in 1975. Schickentanz’s co-drivers were Hartwig Bertrams and Reine Wisell.
