The Le Coq Sportif logo (1950) shows the rooster, spurs out, crowing at dawn. He is inside the blue triangle symbolizing the three controlling members of the company. In 1965 a more modern logo came out, again with the rooster, sun and triangle adding the French flag in the background. Since that time, there have been 6 additional revisions all with the rooster and blue color, and most incorporating the triangle.
