(AI generated): Vintage Soviet-era poster depicting Lenin’s face behind barbed wire, symbolizing imprisonment of nations. Text reads: *"СССР – в'язниця народів"* ("The USSR is a prison of peoples") and *"Братерством єднас нас Леніна справа!"* ("Brotherhood unites us—Lenin’s cause!"). Hand-drawn stars and waves add artistic flair. Likely from the 1960s–1980s dissident movement in Eastern Bloc.
