This is an official commemorative program from the 1997 Don Mattingly Day celebration at Yankee Stadium. Included are the official program , the full game ticket, official insert, and pictures I took while from a distance of the day to capture the special day. It is a hard to find all these items in one auction. Any Donnie baseball fan would love to add to their collection. The program is in mint grade and is an original, officially licensed piece of memorabilia. It is a must-have for any New York Yankees or Major League fan. The program was manufactured in the United States and is a great piece of sports history.
