Sheffield, Waveland, Clark and Addison may sound like a law firm, but that quartet of names actually represent the four streets that border venerable Wrigley Field in Chicago - the oldest and perhaps most revered ballpark in baseball. Here are the actual metal street signs from those four intersecting streets that baked in the summer sun throughout the 1970s, with the Waveland sign actually having witnessed dozens of home runs land on the street it identified. Three of the signs measure 36x7", though the Clark St. sign is only 28-inches wide. Each was originally obtained directly from the city itself after having been replaced, and all have been mounted together for a wonderful display.
