Another prolific artist in Porto is Costah. What is really enjoyable about Costah’s art is that he has embraced the whole edgy culture of street art and seems to combine legal with non-legal walls and is equally at home with paste ups as he is with spray paints.

This cat, painted on a derelict building on a steep hill just north of the river is a really classy piece. Just by looking at it, you can see straight away that it is painted by someone who knows and understands street art. The stylised cartoon cat is a real charmer and seems to fit in so well with the sun-baked wall it is painted on. More too from Costah to come.
