1.5" with photo of vehicle in dark blue plus yellow accented spoke wheels. Names Columbus, Ohio dealer. Right side from 1-3 o'clock has pair of slight hairline impressions in the cello which take on a very faint gray tone. On the back there is no paper and along the left side collet there are six tiny cello splits darkened with age but laying perfectly flat. Both front and back defects are minor considerations on a rare button displaying NM. We know of only two Cadillac buttons that pre-date this and this is the earliest to show a vehicle.
