Will the artist show up to exhibition of his work?

A major exhibition of Banksy's works opens in Rome and, as ever with the secretive British street artist, there is mystery attached.

What will he make of a project he has not been involved in? Will he show up incognito? If he doesn't approve, will he make his displeasure known on the walls of Rome?

The collection of more than 100 Banksy paintings, prints and sculptures sourced from private collections around the world is being billed by organizers as the first time such a large collection of the artist's work has been brought together in a curated, museum exhibition.
