I have on my wall an excellent poster giving all sorts of statistical data for Grand Prix racing from 1950-1989. The problems are that the poster suffered some water damage some years ago and, of course, is rather out-of-date now. It was done by a fellow in L.A. named Zvonimir Jovanovic who once ran a Porsche 911 in the Riverside 6 Hours. Does anyone know this guy or what may have become of his posters? The Culver City P.O. Box on the poster is long obsolete and search engines have been of no use. An updated version of this poster would be dynamite!
