Hi,
This is my first post, as I'm new to the forum. I have three Sinclair road maps one is for Kansas and dated 1932 that was easy to see. The other is for Arkansas, Louisiana and Mississippi and I can not find a date on it except for the listing of the towns for each state it shows a population estimate from 1934, so I'm inclined to think it is from 1934. Is there anywhere else on the map that would have a year on it? The 3rd map is also Sinclair for Central and Western United States, again no obvious date but the populations are based on the 1970 census or later. So again does that mean that the map is from 1970? I have photos, but couldn't figure out how to upload them to this post, sorry.
Thanks
