Information on period pilot maps

There seems to be some sort of Communication Breakdown going on here. Let's take a closer look at Luthier's post and see if we can discern the secret meaning.

Hmmm. . . pretty complicated,. Let's cut out some of the unnecessary stuff.

Perfect!

What Material? As in what did they print the maps on?

a. Paper
b. Laminated paper
c. Rayon
d. The pilot's arm (tattoo)
e. Silk
f. Nylon
g. Deli meats

They are not asking you what to put on the maps, they are asking what to put the maps on!

Things they don't need:

Maps from AFTER the Battle of Britain.
Non-Pilot maps. (maps not used by pilots)
Pictures of the Map's Content.
Incredibly off-topic Italian Babbling about post-war maps.

If you don't know what the maps were printed on, then posting a picture of 1943 Poland is not going to help.

Personally, I'm probably going to rule out silk/rayon/nylon or any other fabric since the pilots didn't need to hide their flight maps and required something foldable but semi-rigid so they could see it properly. Take a tissue, draw a picture on it, then try and read it with one hand. Odd are, the material they are looking for is some manner of paper/laminated paper, or card-stock.
