London telephone boxes become artworks for Childline
A series of old-fashioned telephone boxes are to be placed around London over the summer.
The boxes - nearly 100 in total - will not have phones in them or be red in colour.
Instead, they will be decorated by artists and designers and then sold off to raise money to support 25 years of the charity Childline.
David Mach and Lauren O'Farrell are among the artists taking part.
