....any one got a tip on how to make that?

Real model sells a set if I remember correctly.

I found a website with WW2 maps in the area and year I wanted and then scaled down the image to fit a 1:35 map case.

Here is the old Tamiya 1:35 Kubelwagen, the map went into.

Try here lots of printable stuff

You can also do a google search for maps and print off 'real' maps.
