I read the text on the note (somehow I only think of doing that now…), which say the note is valid as Danish currency, from a month AFTER the reunification until the 1st of Fenbruary 1921.
So maybe we can make the assumption of the “18th of April, 1920” being the “law text” validation date? If that's the case, I can agree with it being moved to Denmark :D
I'll make a transciption and translation now, for the two banknotes's pages.
Hopefully the referee will validate it and add something on here? :D
I have a soft spot for origami paper cranes.
Read or watch about "Sadako Sasaki and the Thousand Paper Cranes".
Spread a little peace and happiness wherever you go :)
