One of London's iconic statues the girl and dolphin. Thousands of tourist photograph it every year generally from the other side so Tower Bridge is in the background.
Sculptor David Wynne also did the boy and the dolphin, that is considered to be the better of the two. This one is in Chelsea. He used his 10 year old son for the model when he created the piece in 1961. A rather sad plaque was added in 1999 when his son died.
