The is the 2nd Certificate we have for sale issued on a different date to the same person - but for a slightly different rank. Presumably a promotion.
A nice original WW2 German Railway Award Certificate printed on card to a Railway Assistant.
Dated June 1940 and issued in Koln it appears to be a promotion or appointment certificate.
It is an impressive item and although not very clear on the photographs it has an embossed eagle stamp on the bottom left next to the signature.
It would benefit from being displayed in a frame.
