Recently, I located the "original" Ink on Mylar drawing, done in 1951, of the 1948 Watkins Glen Grand Prix Road Course. This map was revised in 1952, the last year the race on this circuit was held. The original map is in excellent condition. It is highly detailed. A high resolution digital scan was done of this original map. These prints are from that digital file. The print is 27 5/8" high x 18 1/4" wide, the same size as the original map. A Certificate of Authenticity (that the prints are from the digital scan of the original map file) comes with each map. It is an awesome piece of racing history. There are many "redrawn" maps out there, but these prints are from an original ink drawing done in 1951.
