The circular blue and white BMW logo or roundel is portrayed by BMW as the movement of an aircraft propeller, to signify the white blades cutting through the blue sky - an interpretation that BMW adopted for convenience in 1929, twelve years after the roundel was created. The emblem evolved from the circular Rapp Motorenwerke company logo, from which the BMW company grew, combined with the white and blue colors of the flag of Bavaria, reversed to produce the BMW roundel. However, the origin of the logo being based on the movement of a propeller is in dispute, according to an article recently posted by the New York times, quoting "At the BMW Museum in Munich, Anne Schmidt-Possiwal, explained that the blue-and-white company logo did not represent a spinning propeller, but was meant to show the colors of the Free State of Bavaria."
