You may not believe it but the following work was done in only 10 days. This picture of a tall old woman smoking a cigarrete, surrounded by a duck and a dog is so surreal that it may frighten you. There is a feeling that the drawing might become real at any second. The work, from Polish artist Sainer, is called Crossroads and it occupies the side of an eleven-floor building at Avenida Afonso Costa (Olaias). This is one of the tallest urban works of art in the city.
