Street Art

Tuesday: at Tate Modern for a meeting and took a few snaps of these huge, magnificent images on the front of the building, created for the 'Street Art' exhibition.
The artists are, and I'm not sure which one is who, Blu from Bologna, Italy; the artist collective Faile from New York, USA; JR from Paris, France; Nunca and Os Gêmeos, both from São Paulo, Brazil and Sixeart from Barcelona, Spain.

This is how they look from St Paul's, image from Google.
