I looked up the coordinates and it's south of Neubrandonburg, Germany. The words on the map seems to be Polish? What a journey it must've had for a Polish map on Germany ended up as a German envelope.

i think its a military map. in the lower right you can see words on German, English and something eastern.

I had some note pad by the same brand, and its quite nice paper, not the usual printer paper, but smoother. if feels high quality. always wondered what's the name for this paper. maybe i should search for this note pad...

I resolved the ISBN printed on the reverse side. Took some trial and error (some 30 possible options unless you can read barely-visible EAN barcodes by sight) but there is a check digit so I didn't have to search online for every combination.

Nope, it's a regular topographic map you can buy for €8 or $10. They're published by a government body and the data is freely available online, which you can use much like the OSM database.

You went above and beyond!

I believe you are correct about it being a military map. The visible Polish(?) text is part of the map legend given in German and English.

Yup, Polish. But this is pretty much what generic maps look like in the Czech Republic so probably not a military map.

Edit: It was not hard to find the specific publication. See my other comment.
