Graffiti in Rio

I'm writing a novel about a graffiti artist in Brazil so this story jumped out at me. Some people took advantage of maintenance scaffolding on the Christ the Redeemer statue in Rio, and painted on his head.

It's a heck of a target, and if it'd been done by an artist, it'd be pretty cool... But this is pichacao, scribbles, a style frowned upon by actual graffiti artists, and as such, it's just a mess. Somewhere in a corner of my brain, Mateo Amaral is fuming.
