These are two citations (urkunden) from the same man for the Gold Treue Dienste cross for 40 years loyal service.
One is for the medal itself, the other is a congratulationsetter from the Reichsverkehrsminister to congratulate the recipient with his 40 year jubilee and recieving his medal.
The citations belonged to a man named Wilhelm Soetebeer from Hamburg/Altona, who was a bookbinder (buchbinder) for the Deutschen Reichsbahn.
It’s hard to find a double set Treue Dienst urkunden from the same person.
Both citations are on A4 format and are in very good condition!
