It's the fifth anniversary of Diageo's Arthur's Day, a promotional event for Guinness. It's getting some stick this week, but that's another thing.
I was over on the D&AD Facebook page and spied these posters for the first time, designed by AMV BBDO about 13 or 14 years back. I think they're a great example of how good ideas don't need embellishment.
They won a yellow pencil for "consumer posters" in 2000.
