There's lots of pretty and colourful graffiti in Rio, these photos are of street art in the Santa Teresa area.
There was lots of amazing street art in the city centre, but I didn't take photos. As I was in Rio during a time of strikes and protests and I obviously look like a foreigner, I took the advice of my friend's Brazilian husband and didn't take my camera out on the street. I'm not normally nervous about that kind of thing (I always think I'm just as likely to get mugged in my home town as in a foreign city), I don't feel like anything bad would have happened to me if I had been overly touristy, but I didn't want to take the risk.
This isn't street art, but a little painting my friend did for me the morning before I left.
