Apparently no one knew it was a Banksy when contractors moved in to begin demolition for dozens of new homes.

The mural, Morning is Broken, showed a young boy, with a cat at his side, opening corrugated iron curtains at the site in Kent, England. The house, built in the 1500s, was approved for destruction last year.

“We had no idea it was a Banksy. It made me feel sick realising it was a Banksy—we were gutted,” contractor George Caudwell told KentOnline. “We started demolishing it yesterday. The landowner watched us do it and didn’t know either.” (Images are from Banksy’s Instagram, here)
