interestin wooden plate - Erinnerung an den Einmarsch in das Sudetenland

[Dedman]

Hello gents,
I know here is no direct connection to SS, but don´t know where else to post this.
This is the first time I see plate with this inscription, so want to ask you if you can tell me more about these commemorative plates...
I have seen many "cultural" plates, but this looks to be something different.

Thank you!

Nice killer piece!
