Reverse graffito/graffiti

[Benjamin Barrett]

Reverse graffiti (http://en.wikipedia.org/wiki/Reverse_graffiti) is the result of cleaning the dirt off a wall to create art.

In addition to the Italian Wikipedia (http://it.wikipedia.org/wiki/Reverse_graffiti), I see "reverse graffito" at http://www.austro-arab.net/en/magazine/magazine/article/kunst-beginnt-auf-der-strasse/ and it's also used in numismatics (along with "obverse graffito").
