The mural was painted by Diogo Machado, AKA Add Fuel, who happens to have been born in Cascais.
I like his style of painting using stencils to create the traditional look of the blue and white Portuguese tiles. With this specific mural I didn't like the lady's strange duck face.
I actually met the artist when he came to Perth to paint one of his murals at Curtin University during Perth Form 2016.
