The Semicentennial Commemoration Seal was designed by Jerry D. Kelly, Manager of the Publications Bureau of Tech Information Services.  The five pentagon blocks each represent a decade, and frame the Lone Star of Texas in the center.  Texas Tech’s colors are black and red, so in this version of the seal black represented past decades, while red represented the current one.  According to a 1972 issue of Tech’s student newspaper, the University Daily, the sum of the blocks represented the foundation on which the university would build its future.
