Can we limit election posters to certain zones?

Now that the general election will be shortly upon us I have a suggestion to make in relation to the eyesore that is election posters.

Rather than plastering every lamp post, traffic sign and ESB pole (basically every stationery roadside object) with their air brushed smiling faces, making promises to save the universe with their forward-thinking policies, posters for all candidates should be limited to one designated area on the approach roads to every town and village as well as one position in the centre of urban areas.

During the last European elections I saw this understated practise in effect in Italy and mighty impressed by the suitably subtle locations of the promotional photographs.
