Banksy has installed his new work in the Walker Art Gallery in Liverpool, that accepted it without hesitating.
The street artist vandalised an existing bust of a priest putting bathroom tiles in place of the priest's face, to create a pixelated effect, as the pixelation used in media to prevent identification.
This work has, as every artwork by Banksy, a deeper meaning: it is actually a response to the child abuse scandal in Catholic Church.
