In the NS era, archaeology was used for a lot of propaganda things, usually to show that Germans are The Best Thing Ever and everybody else was, at best, second grade, and that from the Stone Age onwards. Or so. (This, by the way, is said to be one of the reasons why German archaeology after the war became this hard-facts-only science that is rather sparse with interpretations, if compared to how things are done in other countries.)
The Kreismuseum Syke is working on a case that will give some information about archaeology in that era, and while doing the prep and research for that, they stumbled across an interesting history surrounding a Thanksgiving present to Hitler. If you read German, you can follow that story in a digital exhibition on the museum website. (If you don't read German, you're welcome to look at the pictures and old letters there, but the whole thing is heavily reliant on the texts - and it's quite interesting how the writing styles changed over time.)
I think it's a very good idea to do that exhibition case, and the digital exhibition too!
