Michigan "State Reward Roads Maps" 
1912 to 1946
These one-sided maps appear to have been appendicies to the Biennual reports of the Department of Transportation. (It is not likely these maps were used by motorists, but used by the authorities to track the progess in road improvements in various counties.)
