Symbol and corporate mark as seen on most Mazda cars from the Mazda R360 until 1975.

Between 1975 and 1991, Mazda did not have an official symbol, only a stylized version of their name; the previous blue "m" symbol was still used in some dealerships up until the 1980s, but later on a plain blue square next to the Mazda name was often used on dealer signs and documentation
