Show off your vast Cubs knowledge with this Chicago Cubs Shawon-O-Meter T-Shirt from Obvious Tees! The Shawon-O-Meter sign debuted in 1989 when a couple of young Cubs fans created a sign showing Shawon Dunston's current batting average, updated after each at-bat. The sign survived years and became famous across Chicago in the early 90's. This shirt features that same iconic design printed on a comfortable tagless t-shirt. The shirt is made of a high-quality cotton/polyester blend and is machine washable. All Obvious Tees are designed and printed right here in Chicago.
