Thanks Emma, it does seem like splitting hairs to start differentiating types of advertising!

Hi Vicky, a panneau 4/3 (in metres, as you say) is definitely about advertising. This is probably a "permanent" one that says "Kiloutou left at next roundabout"...It's still an ad though.

Thanks, Kimberly. I'm just not sure that those signs you see (bearing the name of the shop and maybe a simplified map / turn right / 500m etc just before you get to a big shopping centre park) would be called billboards, which seem to me to be more about pure advertising. But what do I know!

I like 'secret shopper' — makes it sound as if they're 'in the closet' :-))
