The poster measures 12 x 18 inches and was printed in 1943 by the Assistant Chief of Staff, Western Defense Command and the Fourth Army.
The poster was distributed by the 29th Engineer Battalion, (Topographic). During the war, the Battalion was largely responsible for mapping the Olympic Peninsula and Puget Sound regions of Washington State, and helped with mapping the route of the ALCAN Highway that traveled through Alaska and British Columbia, Canada.
The illustration of Hitler is one that parodies caricatures of the Nazi leader found in Disney's Education For Death and der Fuehrer's Face.
I am looking to add one of these posters to my own collection, so if you have one for sale or know where I can find one, please email me.
