PWPW produces these promotional test pieces specifically for trade exhibitions and security printing conferences — they are never tendered as currency and carry no face value. The Violin note from 2010 belongs to that tradition of demonstration material, intended to showcase the Warsaw facility's in-house substrate and holographic capabilities to potential government and central bank clients rather than to circulate in any economy.
Engraving by Jan Maciej Kopecki on a hybrid substrate is the technical detail worth noting: the combination of intaglio-quality linework with OVI and guilloche on non-paper composite was, at the time, a pointed argument that PWPW could compete with Giesecke & Devrient and De La Rue on high-security specifications.
