^I agree. Unlike, say, Spacing types who oppose advertising at all costs I consider wall ads to be part of the architectural fabric of the city. I love those giant painted wall advertisements and I think it would be a great way to kill two birds with one stone: covering up an ugly wall and generating some revenue at the same time.
Though "Spacing types" would be more likely to rally for a faded old party-wall Coca-Cola ad than not...
