A 1960s children's playground sculpture in Birmingham has been listed by the government.
The fish-shaped sculpture, in Curtis Gardens, is said to be the last surviving work in situ designed by the sculptor John Bridgeman.
It has been listed at Grade II by the Department for Culture, Media and Sport on the advice of English Heritage.
English Heritage said the sculpture was "an important piece of public art".
'Enjoyment and appreciation'
The work, in concrete, was one of a number of play sculptures commissioned for post-war public housing estates in Birmingham.
Bridgeman, who was born in Felixstowe in Suffolk in 1916, was the head of sculpture at Birmingham College of Arts and Crafts until 1981. He died in 2004.

He was known for producing works - often in bronze - inspired by his experiences in World War Two in which he served in the heavy rescue section. One of his best-known works is the Madonna for Coventry Cathedral.
An exhibition held in Leamington Spa, Warwickshire - the town he retired to - in 2013 sparked a huge interest in his work and led to Warwick District Council working with English Heritage to have the sculpture listed.
Deborah Williams, from English Heritage, said: "The play sculpture in Curtis Gardens is an important piece of public art designed specifically for the enjoyment and appreciation of children.
"Designed by the noted artist John Bridgeman, its tactile and sculptural qualities can still be enjoyed and as a rare example of a play sculpture still in its original location, it fully merits listing at Grade II."
