Giesecke+Devrient's demonstration notes exist purely to showcase security technology to prospective central bank clients — they circulate at trade exhibitions and sales presentations, never through any monetary system. This example from 2022 carries the "Dancer" motif, a recurring character in G+D's demonstration series used specifically to show motion-effect holographic and optically variable features under different viewing angles. The Louisenthal facility, G+D's dedicated security paper mill in Bavaria, produces the substrate itself, meaning the paper and its embedded elements originate from the same site before printing — an unusual degree of vertical integration that few commercial banknote operations can match.
