First off, If I am wrong with any of the writing I am sorry, I have not used the language in so long and am pretty rusty.
(This is Fictions' puppet)
This is a commemorative banknote (which is not actually worth anything in either country) it was made by a joint team of designers from TBN and TBS for the anniversary of the revolution in the year 2000. In the year 2000 the two countries signed a peace treaty, this note was not only a commemoration of the revolution that caused the nations to be the way they are (yes it is considered a good thing) but the fact it is a joint project was said to show the "new cooperation between our two nations".
The two men in the picture are the original revolutionaries who then went on to rule their respective countries (the country used to be one before it was divided) the picture itself is a famous one which showed the two together in the early days of the revolution when they still got along.
