Yuppies on the wall

I discovered this piece cutting through the Plaça del Sol, the Grand Place of Gràcia. It had already attracted the attention of about three or four other aficionados, so I had to wait in a queue to get this shot. It was a huge piece as well, about the size of a small garage door. I imagine that it is a message against the gentrification of Gràcia. It was also quite short-lived; I passed by again nearly a week after taking the picture and not a trace of it was to be found.
