I'm not sure if this map would be located by searching any of
the on-line catalogues or paper data bases so am posting it here without
checking those.
Map of the State of Ohio, by Rufus Putnam. P. Wightman,
Sculp. Scale [of original] 20 miles to an inch [1:1,267,200]
Scale of the facsimile ca. 1:1,200,000, essentially full
size.
The facsimile appears on the verso of the 1953 Ohio Official
Highway map.
I'd like to know if it does appear in data bases because if
not, there are other Official highway maps with facsimiles of early maps on the
verso and a listing of such occurences would, I'm sure, be useful to
researchers.
