From the beginning, graphic designs were used to tell different teams apart. An Old English letter was worn on the fronts of baseball uniforms on the chest. This style is still being used today by the Detroit Tigers and their Gothic style "D" on their home uniforms. Road jerseys were able to tell the city the team it is from, as with the Tigers wearing the word "Detroit" on their road uniform shirts meaning the team's home city is Detroit, Michigan. Some early examples are a small red tiger on the black cap of the uniforms of the Detroit Tigers in 1901, as they were officially the Tigers from the beginning; and a bear cub logo on the Chicago Cubs' uniforms by 1907, as that unofficial nickname later become the official name of the baseball club. In another famous example, the Boston Americans (an unofficial name that made it easier to tell different teams apart) used the Nationals' red stockings in 1908 since the Nationals did not use them anymore. They have been called the Boston Red Sox ever since.
