People in Hull are being asked to take part in a mass naked art event as the city continues to prepare to be the UK City of Culture.
The city is to be the latest to host a one-off installation by the American photographer Spencer Tunick, who is known for his images of masses of naked people taken at locations all over the world.
The installation will be made on Saturday July 9, when the weather will, hopefully, be a little warmer and drier than the the current conditions on the east coast of England.
And it will be unveiled in 2017 when Hull is the UK City of Culture.
Organisers say Sea Of Hull will give hundreds of people the opportunity to become part of the art work.
Participants covered in specially formulated cosmetic body make-up will position themselves in front of Tunick's camera in multiple colours of the sea to create abstract shapes separating the body from the pavement in dramatic ways, they said.
New York based Tunick has created more 90 installations at landmarks and cities including the Sydney Opera House, Place des Arts in Montreal, Mexico City, Ernest Happel Stadium in Vienna and Munich in Germany.
He said: "I'm very interested in the history of the city and its place as a seafaring centre and its relationship to a rich maritime past.
"It intrigues me that in some places where there are major streets or parks today, previously there was water. To reflect this I'll be using body paint so that the massed people create the idea of a sea of humanity flooding the urban landscape."
He said: "This is a wonderful opportunity for anyone interested in art who wants to pose nude but is modest. The body paint will help many participants to overcome their inhibitions - after all, they will still be covered in a way."
Kirsten Simister, curator at Hull's Ferens Art Gallery, said: "This is more than a commission. It's an opportunity to involve people directly in an amazing live, performance that will temporarily transform the city."
She said: "His new body of work will form part of an exhibition in 2017 and will also be purchased for the permanent collection. With hundreds upon hundreds of people coming together to be photographed, Sea Of Hull anticipates the exciting things to come at the Ferens next year."
The artist will create a second installation on Sunday July 10, inviting a select group of participants from the installation on the Saturday to take-part in another event in North Lincolnshire.
Anyone over 18 can take part. All participants will receive a limited edition photograph in exchange for getting involved
