Cadbury Wispa Gold
Cadbury used JCDecaux Innovate to promote Wispa Gold in a live PR stunt.
Cadbury invited the public to take part in an online competition to design a poster which would be painted live on a London billboard site by world famous artist, Rolf Harris.
The winning entry was a marriage proposal which Mr Harris dutifully painted in front of an audience consisting of members of the public, press and of course the unknowing bride to be. The surprise event unfolded as planned, leaving the happy couple with the memory of a most unique wedding proposal.
Where next?
