This is a rare original 'WH Festungsbau Dienstbuch' (Wehrmacht Fortress Builders Service Book). The 'WH Festungsbau' was a part of 'Organisation Todt'. The booklet was issued on 23 May 1942 to a member of the 'Festungs-Pionierstab 17', the booklet is complete with portrait-photo. Only a few entries have been made. Nice example in good used condition!
