Dino D'Santiago: 'I started making pornographic drawings and displayed them on the walls of the house. When I went to work, my parents would put The Last Supper back up'

'It was either pornography or a picture of Tupac or of Salvador Dalí. My father would cross himself, but he didn't forbid it.' As he opens the exhibition 'Portal do Retorno', Dino D'Santiago recalls, at Posto Emissor, his early steps in drawing.
