Guitar Sale, Charing Cross Road
A good example of the laid-back, chilled-out, ee-zee human billboard.
Find a nice solid object to lean into, shove the pole of your billboard in your back pack and with both hands free you're able to light up a cigarette, read a paper and watch the world go by.
Experienced 'leaners' can manage such an air of nonchalance that it'll look like the billboard hasn't actually got anything to do with them at all!
