i came across a website that i thought to be pretty interesting, and informative. below us a copied section from the site, something that i thought a few ppl might be interested to know.....
"The circular blue and white BMW logo, which has not been altered throughout the company's history, does not in fact symbolize a spinning propeller according to a BMW spokesman Joerg Huebner (although the imagery did appear in post-WWI advertisements). The BMW roundel badge is believed to have been partially derived from the logo of its predecessor company Rapp Motorenwerke, while ultimately taking on the colors and checkers from the arms of Bavaria (fusilly in bend argent and azure)."
below is the link to the site where i copied the above. its long but worth the read IMO.
