"The Old Gray Lady of 33rd Street" hosted its last baseball game in 1991 and was finally demolished in 2002, Prior to that, Memorial Stadium was known affectionately as "The Largest Outdoor Insane Asylum" thanks to its crazed fans. The rare heavy metal sign offered here actually hung outside the ballpark and is in EX condition. Measuring 18" x 24", it reads: "ORIOLES ROUTE KEEP RIGHT" and pictures the classic Oriole bird swinging a bat. "O" what a collectors' item!
