The idea was first used for smart in 2004 to highlight how the small cars can fit into spaces that standard cars cannot, using seven 2.4x2.4m single-sheet vinyl posters on JCDecaux sites in Birmignham, Glasgow, Manchester and London.
Printing, production of framing components and installation was managed by JCDecaux Innovate.
The mini billboards are accompanied by a national 48-sheet and digital outdoor campaign, along with press and online activity.
JCDecaux sales managing director Spencer Berwin said: "The 2010 campaign operates in a very different media environment [than in 2004], yet still deploys 'traditional' outdoor for stand-out and for reaching a mass audience with digital outdoor adding a new immediacy."
A Brabus tailor-made concept is featured on the mini billboards, which allows customer to customise their car from a palette of 18 colours, with a range of upholstery options.
Mini billboards highlight space saving for Smart car campaign
Car marque Smart has launched a campaign reprising its mini-billboard concept - billboards that fit in between the spaces of standard outdoor adverts.
