There really are some awesome ones aren't there? Just thinking about DiS' posters for summer festivals and dug out this one, which is probably my favourite: http://pinterest.com/pin/273030796129430359/

We had some really nice ones for Great Escape last year http://drownedinsound.com/news/4142586-dis-to-co-host-after-party-on-the-fri-night-of-great-escape

What posters do you own/covet?
