I’ve spotted this stencil at a few places around Aveiro, ‘Em cada esquina um amigo’ (‘On every corner a friend’) is the first line of Grândola, Vila Morena, a song by Jose Afonso (known as ‘Zeca’), and the image is of Zeca with his fist raised in the salute of the revolution against the fascist government in 1974.
Zeca was one of the most influential folk and protest musicians in Portugal, and the song was used as a radio signal during the military coup of 25 April 1974, which led to the Carnation Revolution and the fall of the fascist regime.
Afonso and ‘Grândola, Vila Morena’ became symbols of anti-fascism, as well as of both the Portuguese labour movement and political left, and it is common in Portugal for the left in particular to stencil art anti-right wing/anti-fascist messages.
