This month, teachers and students at the Bridge Farm Primary school in Whitchurch, England learned about the art of surprise. According to The Daily Mail, the students recently chose to name one of the school's houses after the elusive Banksy. And as a thank you, the anonymous street artist painted a mural on the side of a school building, depicting a child rolling a flaming tire with a stick.

In an interview with SWNS TV (shown above), the caretaker of the school said that he found the 6-foot-tall mural—which features Banksy's signature—shortly after arriving to unlock the buildings. He also discovered a letter from the artist.

"If you don't like it feel free to add stuff, I'm sure the teachers won't mind," read the handwritten note. "Remember – it's always easier to get forgiveness than permission."

This isn't the first time the artist has made a scene for a good cause. In 2014, he painted a doorway in Bristol and left a note that promised the piece to a nearby Boy's Club that was struggling financially. Like that piece, the mural at the Bridge Farm Primary school will leave a lasting impression. According to the BBC, head teacher Geoff Mason says the school's officials have "no plans to sell it."
