I’d get a couple of spray cans of paint and take care of it one dark night.

I’d get a couple of spray cans of paint and take care of it one dark night.

A couple of cans of spray paint wouldn't cover that wall/image of around 400 sq. ft. by my eye. It would take a case of 12 at least. And the image would likely bleed through.

The people who own the property can buy a gallon of B-I-N or KILZ (covers about 400 sq. ft.) and roll it on.
No bleed through and it dries in 15 minutes. Bye bye Banksy.

Yep. “Gee, I have no idea who might have done that. Damned hooligans.”

Also, note to author: There’s no need to put [sic] after each British spelling of a word.

The art increases the value of the house by a lot.

I would buy 4 standard sheets of clear plastic (or plywood)

And cover it. Pretty sure I could do that for well under 1000 dollars

yup, cost of a bucket of paint at most.
