Not long after its creation in 1921, GAO adopted a seal for use on official documents. This seal was updated in 2004 to reflect the agency's new name. At the center of the seal is a shield divided by a band with 13 stars representing the 13 original states. Below the band of stars is the U.S. capitol dome, indicating GAO's role in the legislative branch. Above the band of stars are (1) scales symbolizing the principles balance and fairness on which the agency is based and (2) an account book, quill, and key, which refer to the agency's role in evaluating how taxpayer dollars are being spent. Completing the design are a classical garland and an eagle grasping the American flag.
