(Panama) Gray's Aero View Of The Panama Canal
It was indeed the "World's Greatest Engineering Feat" at the time and this raised relief map for the path of the Canal conveys the surrounding terrain as well as the path from ocean to ocean. Celebrating the event of the opening, it is in its self contained folder, which includes the elevation profile, as well as history of the canal.
Condition is very good for the map, minor fold separations for the folder. Image size is approximately 14 x 4.5 (inches)
