This is a quite large (and thick) stone plaque, made for the “liberation” of the Rhineland in 1930: Zur Befreiung der Rheinlande 1930.
The size is approxmately 24 cm and the thickness is 2,5 (at the thinnest area) and 3 cm (at the thickest area).
This is a very impressive plaque that is quite hard to find. The dark green colour gives it a great appearance. This would make a real eyeatcher in e.g. a glasscabinet.
In good condition, there are a few scratches and such from age and handling, but nothing disturbing and actually in quite good condition!
