Changing the clutch in the Green '41 Buick - July 1962

Notice the old black on yellow California plates. Later in the sixties they switched to yellow on black for many years. Still later they switched to yellow on blue plates until they had so many cars registered in California that they ran out of numbers and added a seventh digit. Somewhere in there they issued blue on white plates while retaining the validity of the older ones going back as far as yellow on black.

When I restored this same car in the mid-seventies the yellow on black plates were still valid so that is what you see in the later pix.
