Tide Water Associated Oil Company Map of Oregon - Idaho - Montana. This is a folded road map copyrighted by The H. M. Gousha Company. I have searched but I cannot find a date on it anywhere. But based on the great graphics and the history of the company I believe this is from somewhere in the late 1940s to the early 1950s. When open it measures about 26 3/4"  x 18", folded about 3 7/8" x 9".  The text on the outside of the map mentions the following companies, products & services: Tide Water Associated Oil Company; AroTane Gasoline; Flying A Gasoline; Veedol and Tydol Motor Oil; Veedol Safety-Check Lubrication; Federal Tires and Tubes; Top Quality Auto Supplies; Friendly Associated Service.

Overall good condition for age. Some wear along edges and creases,  some dark smudges on the map (see the eastern end of Oregon in photo), other light smudges, etc.

I am always happy to combine similar items (or items that will pack well together) for possible savings on postage. Please let me send a combined invoice before making payment.  Media items (books, etc) can only be combined with other media items.
