The triangular shape design of the insignia, disc, and star
are adapted from the Ohio state flag. The buckeye, symbolized
by the disc, is the seed of the state tree from which Ohio
receives it's nickname of "Buckeye State." The star represents
Ohio's statehood in 1803 as the seventeenth state of the union.
