The mark consists of the letters T-L-G-C. T-L-G-C is displayed twice: once in white letters on the left side descending diagonally from upper right to lower left. To the right of the white letters is a mirror with a border that is depicted with a silver rectangle within a silver rectangle. The rectangles look as though shadows are being cast on it with light gleaming only on the middle left and right panes. The inside of the rectangles house the second set of T-L-G-C descending from upper left to lower right of the innermost rectangle. This T-L-G-C is a silver stencil version of the other and gives the illusion of a mirror image corrected. All letters and shapes are on a black backdrop.
