The secretive graffiti artist had left a spray-painting of a child holding a stick and chasing a burning tyre on the wall – the image is believed to be a modern take on hoop rolling, a popular game played by children during the Victorian days.
The six-foot high artwork also features a flower and a small house with ‘Banksy’ signed to the bottom left of the brick building.
A further note from the artist, pinned behind the mural, said: “Dear Bridge Farm School. Thanks for your letter and naming a house after me. Please have a picture.
“If you don’t like it feel free to add stuff, I’m sure the teachers won’t mind.
“Remember - it’s always easier to get forgiveness than permission. Much love Banksy.”
