The Porsche 911 Carrera RS posters feature the car that many consider to be the most classic 911 ever built. Designed to meet motorsport requirements, the RS – meaning Rennsport, the German word for race sport – featured a larger engine than the standard 911 S, stiffened suspension, and an iconic ‘ducktail’ rear spoiler. In total, 1,580 were made between 1973 and 1974, all of which qualified for the FIA Group 4 class.
