This is a very cool original SCCA Championship Poster.  Here's the history, Oregon International Raceway was only around for 2 years in Eugene, Oregon. OIR eventually became Portland International Raceway in Portland, Oregon. This is a really awesome SCCA collectible, Porsche collectible, and for Pacific Northwest folks too! Features a 904 Porsche race car, likely from Eyerly Motors in Salem, Oregon. 22 inches tall x 14 inches wide
