Banksy joins plastic bag campaign

Banksy appears to have joined the campaign to ban plastic bags.

The guerrilla artist is believed to be responsible for a new image to emerge overnight on the wall of a north London pharmacy.

The painting depicts two children pledging allegiance to a Tesco plastic carrier bag in place of a flag.

The owner of the pharmacy in Essex Road, Islington, said he was thrilled by his new paint job.

"I just walked into the shop on Monday and, lo and behold, there it was," he told the London Paper.

"I am absolutely delighted - I think it's just fantastic. I've heard how much these works can go for.

"We would consider selling the wall, but not the shop. I think anyone who would want to erase it is crazy. It's a piece of art."
