Warning: You may find some of these images offensive (I do too, except the monkeys). I do not endorse vandalism in any form, or the messages in these pictures. But I do find them intriguing.

Like most people, I generally find graffiti to be both irritating and disappointing. That's usually because it usually consists of things like cryptic gang names and off-colored bathroom wall limerics. Upon arrival in Lisbon, I noticed the Barrio Alto area I was staying was just covered in graffiti. But then I quickly started noticing that there was also a great deal really intriguing, stenciled graffiti. So much that I decided to collect it and see just how many different images there were.
