Aaaarrrrgggghhhh! If it be treasure maps you're seeking.. I can't help ya..
But what I can help you with is, is this offering... but bigger, and with no sea-monster
(see attached thumbnail for the "real deal").
It's the in-game map (not as easy as pressing your printscreen button), except I darkened the lines. I can always throw numbers/letters at the sides of the map if anyone wants aswell.
Take this to a "Staples" or a store similar, and you can get it printed as big as you'd like.
Enjoy..
I know it's not WWII, but it's "our" WWII map.
