A Turner Prize sculpture of a nude man has caused controversy among some schools in Northern Ireland.
The prestigious exhibition opened to the public in Londonderry on Wednesday morning, the first time it has been taken outside of England.
The entries are on show at former Army barracks at Ebrington. Derry is the UK City of Culture 2013.
David Shrigley’s naked model has been avoided by a number of schools because it shows a man urinating into a bucket.
Glasgow-based Shrigley is best known for his humorous line drawings, but also makes sculptures, photographs, paintings and animated films.
His work, which combines jokes and commentary, can be found on greeting cards, in books and in magazines, as well as in galleries.
Schools from across Northern Ireland have been invited to the exhibition.
Ann Murray, the principal of Oakgrove Integrated Primary School in Derry, said: “This particular piece of art is too much for some students.
“We have younger people at the school, so I’d rather have their parents take them to see Shrigley’s piece rather than the school, BBC informs.
