This is a Haus der Deutschen Kunst abzeichen from 1937 + accompanying 1938 entranceticket for the Haus der Deutschen Kunst. Especially the ticket is very very rare!
The 1937 badge was designed by Richard Klein who’s initials are at the right lower end visible.
On the back the badge is maker marked on the pinplate with the name of Deschler & Sohn München. Only a few were maker marked like this.
A very nice little set!!!!
