The Dallas logo, then, has done its job. Maybe too well. The city’s logo, which has been in use since 1972, features concentric D shapes made from three stripes with a stylized tree in the center.

The City of Dallas logo is comprised of a simple curved 'D' design made up of 3 distinct blue lines. At the centre is a green leaf emblem, representing the city's commitment to sustainability.
