The Art School of Peterborough is celebrating its 20th anniversary and invites the public to join them for their inaugural Art Market this Saturday (June 15th)—an outdoor event (in the tunnel arcade of Charlotte Mews). There is no admission charge for visitors. There will be artists and artisans all with original work for sale. There will also be an activities table for the kids and fresh popcorn and candy floss. And a birthday cake.
