Wallace and Gromit designer dogs unveiled in Bristol

The four finished designs are by British designers Sir Paul Smith and Cath Kidston, illustrator Simon Tofield and animator Richard Williams

Four giant Gromit statues, decorated by well-known artists and designers, have been unveiled in Bristol.

The "grand trail" of 70 of the 5ft (1.5m) tall models of the Oscar-winning animated character is due to populate the streets of Bristol this summer.

The four finished designs are by British designers Sir Paul Smith and Cath Kidston, illustrator Simon Tofield and animator Richard Williams.

The aim is to raise funds for the Wallace and Gromit's Grand Appeal.

The 70 giant models of Aardman's famous canine character have been sent out to artists around the world to decorate with their own designs.

The statues will be put on display around the city from July, before being auctioned off in September in aid of the Bristol Children's Hospital.

In 2011, a sale of gorilla statues - which had been displayed around the city - raised around half a million pounds for charity.

Wallace and Gromit's Grand Appeal was formed 17 years ago after a public charity appeal to build a new children's hospital that enlisted the help of Bristol-based animation studio Aardman Animations.
