Photo was taken in Saarbrücken town hall on March 1st, 1935. From left to right:
Bishop Franz Rudolf Bornewasser (from Trier), Bishop Ludwig Sebastian (from Speyer), Josef Bürkel = Reichskommissar for reunion of Saarland, Wilhelm Frick = Secretary of the Interior, Joseph Goebbels = Reichs Ministry of Public Enlightenment and Propaganda.
My guess: Q posted it as a hint towards the relationship of Vatican and NS. The Bishops are catholics!
