The poster and billboard for Yugoslav Drama Theater in Belgrade, Serbia's production of Lorenzaccio (Lorencačo) a play written in 1834 by Alfred de Musset.
Lorenzaccio is a play about Italian politician, writer and dramatist Lorenzino de' Medici (1514 – 1548). Lorenzino lured his cousin the Duke Alexandro of Florence into his apartment with the promise of a night of passion then assassinated him with a dagger. Lorenzino acted for political reasons with the goal to free Florence from a man that many considered to be a tyrant. After the assassination, he fled Florence and a few years later two hired killers caught up with him and murdered him in Venice.
Overall, it’s like a Renaissance Game of Thrones.
