Hungarian Currency in the 20th Century from Post-WWI - Communist era

What you see below is a short history of Hungarian currency, from low denomination korona (crowns, a vestige of the Dual Monarchy with Austria) to the Pengo which slowly deteriorated throughout the course of its life, particularly during WWII and then thereafter, eventually replaced by the Forint in Communist Hungary. What's amazing is that Pengo were still being printed in May, 1945.
