It may be a juvenile prank but my guess is that the author wasn't a juvenile. Nice image, though - our eye is led up the stairs and around the bend at the top by the railing and one really senses the quality of dappled light from the backlit trees and shadows at the base of the stairway.
Tres jolie photo,j aime bcp !
A picture which speaks in so many ways, light and shadows and the big plus: where does it go and what is behind? THe graffiti gives it a temporary identity.
