Here is another original Arbeitsbuch with the second style. Gruber is the only part of the individual's name that I am able to decipher. Please view photographs to see what you think the last name might be.
The Arbeitsbuch was a result of the Labor Law of February 1935 that
required labor registration and the use of the appropiate document. The
purpose of the Arbeitsbuch was to document the work history of each
German citizen. During the twelve years of the Third Reich the
Arbeitsbuch came in three editions. The main dif-ference were the
variations of the cover. On the cover of the second style
the Nazi eagle replaced the Weimar eagle and the swastikas in the
corners were discontinued. This document was for German citizens only, foreigners who worked
in the Reich had to carry a similar book which was printed on a
different color paper and which contained a photo of the owner while no
photo was required in the domestic document.
