This is a (NSB) Nederlandsche Heemkunst “catalog” for cultural runic brooches.
In the shape of a foldable folder, on the front is written: “Sierraden met Oud Germaansche Zinnebeelden” (jewelry with old Germanic symbols).
On the inside are pictures the brooches that were available with a description of their background.
Please note: i redacted the content heavily in red with photoshop, as to not give fakers/copiers an idea. This is an extremely rare to find small folder, that is even here in the Netherlands as good as impossible to find. Everyone knows the brooches, no one has the folder. Now here is the chance to get one and know the content!
Very rare and in good condition!!!
