A good exhibition stand need not cost the earth, but it should attract potential customers in an instant as they approach.

Next time you visit an exhibition, look out for all the quiet stands where there are reams of text and bored exhibitors, then look at the stands where the message is clear: these are the stands that work hard.

Many of the images and work samples are taken from Chris Williams' archives dating back over more than 30 years at QWA and The Teds Agency
