Hi Windrush I remember seeing some excellent examples of mobile shops built in the Glasgow area and exhibited at the 1957, 59 & 61 Scottish Commercial Motor Shows in the Kelvin Hall. They were very well painted in appropriate designs depicting their trade as bakers, butchers or general traders. I cannot remember the names of the body builders now it is so long ago. The Kelvin hall was the place to see the very best of Scottish coachpainters and sign writing art.
