Here's a niche magazine for a very specific topic; Kanu-Sport Faltboot-Sport. From May 20 1939. This is an entire magazine dedicated specifically to folding canoes. Germany was really into camping and collapsible rubber boats for hiking even in the 1930's. If you want something besides the typical military magazines for your display, perhaps its time you got into boats.
I was about to make a comment about how politically neutral it feels, like it was one of the few publications that you could escape into - a world of canoe sports without politics getting much involved. Then I remembered this was an official publication of the canoeing department of the national socialist league for physical exercise.
They seem to have published this quite frequently, sometimes multiple times a month. I guess there was a lot to talk about in the canoe world, Canews if you will.
