The BMW emblem logo is derived from the coat of arms of the state of Bavaria in southern Germany. This first BMW emblem logo, which was registered in the German Imperial Register of Trademarks on October 5th, 1917, retained the basic design of the old corporate logo for Rapp Motorenwerke.
On the other hand, many people believe the BMW emblem logo is a stylized spinning airplane propeller. The BMW ad in 1929 depicts the BMW emblem logo, which was painted with the blue and white colored quadrants in a spinning airplane propeller. The interpretation that the emblem logo expresses a propeller has endured ever since. Then, the ad in 1942, BMW linked the propeller to the emblem logo again. This ad was trying to promote the engine of an airplane built by BMW. For a long time, BMW made little effort to correct the myth that the origin is an airplane propeller.
