This is an Arbeitsbuchs of a person who resided in Germany. It basically is an identification or "workbook" for said person. The Reich brought over 7 million people back to Germany to work on their Various industries and each one would have had one of these books.

It's seemingly real though nobody through pictures can validate this without a notion of doubt. I doubt it was given to your Great-Grandfather rather he found it on his operations. Many soldiers kept memorabilia of other soldiers found and very often would leave eachother gifts and keepsakes in "No Mans Land" for eachother.

Hey folks, I am the other user here.

I know its a work permit for a Polish guestworker, but do you think its real?

Was it standard to give paratroopers on the Omaha drops documentation acquired through Polish resistance in case the landings failed and the troops had to revert to civvies?
