Krause Papierwerke Fraud Prevention
Krause against dishonest traders
Most of the products of Krause Papierwerke come very close to originals. Some are virtually indistinguishable by casual collectors, which creates a risk of my products being sold by dishonest traders as originals. Especially after some minor effort aging them.
As forgeries of German WW2 items is a real plague these days, I felt the need to add some level of protection against such practice. Since March 2018 all Krause Papierwerke products have been marked as reproductions with a big round "invisible ink" stamp that can be only seen under black light. It is not visible under normal light conditions and does not interfere with authentic look and feel of a document. However anyone in possession of inexpensive UV light (available on ebay from ~$5) will be able to identify Krause Papierwerke product.
This will not completely prevent the chance of misuse, but will give potentially cheated buyer an opportunity to demand refund.
Below you can see what to expect - the same 2 products in visible light and under UV.
