25 000 Korona

Hungary's post-WWI hyperinflationary spiral forced the Royal Ministry of Finance into a series of increasingly large denominations through the early 1920s — this 25,000 Korona being among the higher values issued before the entire korona system was abandoned in favour of the pengő in 1927, by which point the korona had become effectively worthless. The commission going to Orell Füssli in Zurich was a pragmatic decision: domestic printing capacity was inadequate for the volume and quality required.

Traugott Willi's engraving work for Orell Füssli during this period was consistently precise, and his name appears on several central European emergency issues of the same decade.
