Cavernous Municipal Stadium, which opened in 1931, hosted its last game on October 3, 1993 when the Tribe lost 8-3 to the Chicago White Sox. While Cleveland fans called the drafty old park "the mistake on the lake," a sentimental crowd of 73,390 came to say goodbye. This cap was worn by home plate umpire Al Clark on that day and autographed by Clark on the inner lining in black marker, with the signature rating a 7, as well as handwritten markings "Clark", "Plate", and "93". The size 7-1/4 cap has a gold "AL" logo and shows substantial game use. It comes with a letter of authenticity from then-Indian coach Jose Morales to whom Clark gave the cap.
