Color of License Plates, 1928-1931

Posted by Ken Smith on March 20, 1997 at 06:41:24

Can anyone out there give me a run down on the colors used on license plates- OHIO 1928, 1929, 1930 and 1931? I have an original unrestored 1930 OHIO plate that is Maroon with numbers/letters in white paint. Is there a license plate color reference book available for all states?
