The Warsaw Uprising Museum is staging a multimedia exhibition showing how the Polish underground movement went about producing forged documents as part of the struggle against Poland’s German occupiers during World War II.

The exhibition features items such as fake identity documents, counterfeit banknotes, stamps, a document-forging set and a walking cane with a hiding place for secret documents. A machine which enables visitors to read documents reduced in size to several millimeters has been built specially for the exhibition. Visitors also have an opportunity to listen to interviews with people who were involved in producing forged documents.

The exhibition is complemented by two multimedia presentations showing false documents and counterfeit banknotes.

The exhibition is being held in conjunction with Polska Wytwórnia Papierów Wartościowych (PWPW) SA, a company that produces banknotes and secured documents. As well as focusing on forgeries, it shows the present work of PWPW and modern techniques used in the production of secured prints and documents.
