This is a nice together belonging group of four passes from Protektorat Böhmen und Mähren (Czech). These Labour bookslets are in the same style as the well known brown German Arbeitsbücher.
There are two brown Protektorat Arbeitsbücher in the group, and one green variation which is from just after the war. Very interesting to see it is in the same style. Lastly there is a black booklet with two extra letters in the group, which appears to be some sort of passport (?).
Brown Protektorat Arbeitsbücher are rare to find, but a grouping like this is not offered often for sale!
In good but used condition, very collectable and a great addition to any Arbeitsbuch collection.
