21. Seattle Supersonics
Year Logo Introduced: 1975
Hornell Anderson designed the last NBA logo used in Seattle. In play from 2001 through 2008, the design brought back the team's classic yellow and green, but didn't hold a candle to the team's second logo—the last to reference the team by the full name of Supersonics and the only one to call out Seattle's distinct skyline (including the famous Space Needle).
