This is a truly awesome display. The original blueprint from the Osborn Engineering Co. of Cleveland dates from 1927 and this particular blueprint is a schematic drawing of the seat castings and straight back seat design to be used at Yankee Stadium. The letter is from Jacob Ruppert, the current president of the American League ball club, and is dated February 14, 1928. The letter is a request for the drawings with which it is framed. The entire display is professionally matted and framed and measures 41 x 44", creating a truly stunning display for your home or office. If you are a Yankees fan this lot is not to be missed. It is thousands of times rarer than a Yankee Stadium seat.
