Viral advertising?

Sorry - I know we really shouldn't post ads on blipfoto, but you must admit this is a quite a unique selling proposition..

Seen by night at a Suffolk roadside, we had to turn back to see if we'd really got the picture - and then got the picture.

(PS this is right up there with my other top Suffolk road-sign Cats Eyes Removed. American-English speakers may have to ask for clarification of this one!)
