This is an unused feldpost postcard signed in pencil by Baumbach during the war. The signature is clear and strong when you are holding it. (I circled the signature with orange, on the computer only) I have NEVER seen a postcard/letter like this in 58 years of collecting! So this is rare! I am not 100% sure if Werner wrote the letter, himself, but I think he did. It has a few small rips in it, because the paper is so thin. It is a regular sized postcard when folded and glued (just like a regular letter) CLICK THE LETTER TWICE TO SEE IT BETTER.
