This original (not the later reprint) 11 by 17 inch pencil art poster is of Englishman Brian Redman's Porsche 917 that he used to win countless races in 1970 in the world endurance sports car championship. His teammate most of the time was Switzerland's Jo Siffert. This #20 car is the 917 that Seppi and Brian ran at LeMans in 1970, with Jo missing a gear while passing the pits and blowing a piece off the engine in front of Porsche motor sports officials. This poster was hand signed by Redman at Porsche Rennesport II at Daytona. This long sold out piece of art work is done by Tom Bucher. If you're going to frame this, then you'll not be bothered by the small amount of masking tape on the rear in two places (held it in place in a poster frame).
