Gable end

These fantastic 40ft drawings by Joe Caslin have been springing up around Edinburgh these past few weeks. This one adorns a gable end on the Cowgate, at the back of the Central Library, visible as you peer down the Cowgate from George IV Bridge. Ian, one of the lovely attendants you'll meet at the front desk as you enter the library, spied the team at work on this one. Magic, he said.
