There's a poster up at the top of Portobello Road in Edinburgh, just next to Morrisons and just down from Meadowbank.
I say poster but actually it's a series of mosaic tiles, making one of those puzzles you had when you were a child where you have to shoogle the pieces around to make a picture.
It started off as a complete jumble about 3 weeks ago and it's almost got to its proper correct picture as we speak. And it's a Honda.
It fits beautifully alongside the TV ad. And is such a charming and imaginative use of a 48 sheet site. I'm delighted by it.
I tried to find a photo on the internet but even flickr isn't yielding anything. You shall have to go see for yourselves.
