This is a period German WWII female cultural rune brooch with Teiwaz rune in it’s centre.
It’s diameter is approximately 5 centimeter (which is large!).
In the centre is pictured a teiwaz/Tyr rune. This is the 17th rune of the old Futhark. Its sound is “T”. The rune stands for the god Tyr.
The brooch is in very good condition and has a functional needle on the reverse. It is very rare to find in this form compared to more available ones.
