In Portugal's 20th-century dictatorship, state censors used a blue pencil to strike through any text, image or drawing that didn't align with the regime. Active for over four decades, it wasn't just a bureaucratic tool. It was a machine of erasure. Poets, novelists, musicians: almost every major name in Portuguese culture knew the blue pencil. And over time, its greatest triumph wasn't the cuts it made. It was the self-censorship it installed in people's minds. That pencil became a symbol of everything that couldn't be said.
On the 25th of April, 1974, it all changed.
