Great scans of overprinting, stamping, and revaluing. Love it! As for notes with the fidgety folds and sweaty finger stains... of the miserable and oppressed working classes... One might say, "Circulation has turned art into artifact."
Sorting out the Yugoslavian Civil War Banknotes... Slovenia, Bosnia and Herzegovina, "Serbia and Montenegro", Croatia, ... The Serbian Republic of Krajina"... ...has any "entity" been overlooked? Vojvodina? Kosovo? Macedonia? Republika Srpska? Herzeg-Bosnia? Western Bosnia? https://i.ytimg.com/vi/Ic5tBXESxl8/maxresdefault.jpg
I figure Republike Srbske is presently one half of "Bosnia and Herzegovina" and the Federation of Bosnia and Herzegovina and is the other half. I estimate the probability of being correct at 83%.
