During the early 1990's, the Socialist Federation of Yugoslavia experienced a series of political conflicts and what were called "The Yugoslav Wars." Since 1995, and the Dayton Peace Accords, Yugoslavia was realigned into seven separate states, Bosnia, Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. Kosovo is still a troubled region with conflict over borders. The problems with the former country of Yugoslavia involve older ethnic and religious ties and are complex.
"Yugo-nostalgia" is present in some areas when people yearn for the socialist system and the security it gave them and many still feel they are "Yugoslavs," a bit like Russians yearning for the "good old Socialist days."
I don't know anything about printing, but I noticed in this poster that there are multiple colors, and I think you have to have a separate plate for each color which must have been difficult. It is striking, though.
