Standard Oil Company of Kentucky made maps from 1923 to 1975. The above set shows Standard Oil Company of Kentucky maps of the state of Kentucky. I am still missing the 1931 map and the 1925-1927 are issued by Standard of Kentucky, but are not of the state of Kentucky. The later maps are Chevron maps as the company became part of Chevron.
