SUPER RARE WW2 WWII Original SECRET Navy Map Mariana Islands Pacific War Japan

Here we have a very rare map of the Mariana Islands for World War 2. This is a see-through map possibly used in submarines. I'm not a map expert, but this appears to be a map that is used on a lighted flat surface in a dark room e. The first image is held up to a light so you can see all the details. Locations on the map include Pajoros island, Asuncion Island, Agrigan Island, Pagan Island, and a bunch of other islands all the way to Guam. The direction arrows and presumed travel path ends in Guam. There are also "supply" points notated.

Highly unusual and super cool! I've never seen one of these before nor will I ever see another again.

Great addition to your map collection! I'm happy to send more pics or answer any questions - just ask.
