Every identity card has a fingerprint on the back of the photograph on which a transparent seal is placed with a special type of glue. The stamp of the issuing municipality is half on and half off the photograph. Special tools were required for a relatively simple forgery. The brass cover was used to detach the stamp with acetone fumes without the printing being damaged. A ‘hinged arm’ ensured that the stamp could be put back in exactly the right place once the photograph had been replaced. Back to highlights
The Germans introduced all sorts of official documents to keep the Dutch under control: work exemptions, bicycle permits, etc.
Forged papers were therefore indispensable for people in hiding and resistance fighters. In 1941 and 1942 the first attempts were made to forge identity cards. The person's name was bleached out, and the 'J' for Jew was removed with a penknife and pasted over. The techniques were improved slowly but surely.
