There are substantial Native American communities throughout Oklahoma. In Tahlequah, in eastern Oklahoma, the stop signs and the street signs are in Cherokee as well as in English. In September 2003, David Backlin found another sign, this one a yield sign. The yield sign appears relatively new, but it harkens back to the earlier yellow triangle that was used until the present red-and-white sign was adopted in the 1970s.
The 85-character Cherokee alphabet was invented by Sequoyah around 1820. The Cherokee Nation adopted it in 1821 and the people quickly became literate.
