Other peoples' jobs hold a certain mystery: who and what is behind some of the products and services that we often take for granted?
See how Quest learns the tricks of the trade from Mark and Micky, two professional billboard fixers who put up those giant advertising posters we all stare at when stuck at the traffic lights. As Quest discovers, it's not easy putting up a poster that measures twelve metres by three metres and comes in 96 pieces.
And don't forget to tell Quest what you get up to in the World of Work. Email your pics to the show to Quest@CNN.com and we will try to use a selection on air.
