The mark consists of four concentric circles. The top half of the second circle is shaded and comes to a downward-facing point at the middle of the circle on each side, with a shaded circle below each point; the bottom half of the circle is not shaded. The shaded half of the circle features the wording "TALK DAT" in capital letters with "EST." in smaller capital letters and "1974", with a horizontal line above each, just above the downward-facing points. The bottom half of the circle features the wording "TALK TEES". The third circle features a series of small lines extending between the line forming the third circle and the line forming the innermost fourth circle. The fourth circle features the wording "T.D.T" in bold capital letters in the middle of the circle, with two horizontal lines on the top and bottom of the wording, extending across the circle.
