The Buick trishield is rooted in the ancestral coat of arms of the automaker's founder, David Dunbar Buick. That crest was a red shield with a checkered silver and azure diagonal line from the upper left to lower right, a stag above and a punctured cross below. The division adopted this on its radiator grilles in 1937. In 1960, the logo underwent a major overhaul. Its single shield was replaced by a trio in red, white and blue—denoting the LeSabre, Invicta, and Electra then in the Buick lineup. Usurped by the Buick Hawk in the 1970s, the trishield reemerged in the 1980s, simplified, but with its same patriotic colors. Today, again representing the trio of vehicles in the Buick marque, the trishield enjoys its even more distilled—and emboldened—monochrome form. Today it is one of the most recognized automotive emblems on the market.
