I believe the above SOHIO maps represent a complete run of SOHIO Maps of the State of OHIO from 1924 to 1985. There seem to be a lot of different editions in the early years, but I think I have shown one of each cover over those years. SOHIO did not publish a 1943 Road Map of OHIO (but I decided to show editions 22-25 in the year slot 1942-1945 because the back cover is different on the two 1945 maps). I included a separate set of pictures showing the 1976-1985 maps.
