Polish Security Printing Works (PWPW) was established on 25 January 1919 under the leadership of Ignacy Paderewski. In 1926 a new building was built, which is still the seat of the Polish Security Printing Works (PWPW). During World War II, there was a conspiratorial group of PWPW employees who produced banknotes and documents for the Home Army risking their lives. For 100 years, PWPW has been our guarantor of civic identity and security of the Polish state, thanks to the production of perfectly secured banknotes, postage stamps, etc. It has been the first time that PWPW has produced banknotes and documents for the Home Army. The presented banknote is another part of the "Independence" series. The nominal value of the banknote refers to the year in which PWPW was created. The watermark refers to the eagle from the first Polish banknote produced after regaining independence. On the reverse side there is an image of Ignacy Paderewski. On the obverse there is an image of the main building of PWPW.
