During the War 

Pictured here is a Chanukah menorah that was made in a forced labor camp in Gogolin, Upper Silesia in Chanuka 1941. The initials: R.A.B.L. on the front of the picture, probably stand for Reichsautobahnlager. The Jews in Gogolin were forced to work on the Reichsautobahn in addition to being used as slave laborers in factories and agricultural projects.
