A shortlist of 300 iconic billboards has been drawn up, selected by an industry panel including PHD chief executive Daren Rubins and ISBA director Bob Wootton, and this has now been opened up to a public vote.
The final gallery will be revealed at the end of March at outdoorhalloffame.co.uk and in PrintWeek's sister title Campaign.
Outdoor Media Centre chief executive Mike Baker said: "Outdoor advertising is an important channel for brands and it's time for the industry to recognise and celebrate the creativity of impact of the medium."
