The mural is inspired by the verse “’Em cada rosto igualdade” (equality in every face) from Zeca Afonso’s song ‘Grândola Vila Morena.’ The phrase conveys the idea that despite external differences among people, everyone deserves and should be treated with equality, respect, and justice. It’s a call for unity, solidarity, and the pursuit of a world where equality is a fundamental principle.

The song was used as a signal during the Carnation Revolution in Portugal in 1974, symbolizing peaceful resistance and hope for a fairer and more egalitarian country.
