The stickers are hidden...

On Monday the stickers will be hidden in the following London locations -

- Under a pile of Metro newspapers at Tooting Bec tube station.

- Beneath the 'Subway' sandwich board at the sandwich shop on the side road next to the 'Plaza' shopping center.

- In a Delia Smith hardback cookery book at Borders, Oxford Street.

- Behind the swimming floats in John Lewis Sports department.

If you find the stickers remember to stick them on poster noses. Or sandwiches (but not real ones.)
