Grayson Perry is taking part in a charity raffle to raise money for a number of good causes in Walthamstow.
Along with artist Jeremy Deller, MP Stella Creasy and children from Whitefield Academy Trust, he is decorating a postcard for Community hub and charity The Mill.
The postcards will be raffled for just £1, and all the mini originals will be given out to winners later on this month.
The postcards have been created in secret and will go on display at The Mill between 9-17 October. The artists name will only be revealed after the raffle tickets are won.
The proceeds will go towards a number of good local causes including a homeless shelter.
