They're lovely. They get nicked. That's the trouble with great poster designs.
It's always happened. I noticed this at first hand when I asked the amazing Hunt Emerson to do a brilliant, gently mocking design for Project X Presents. Hunt's poster placed West Midlands hipster heartland Moseley at the centre of the world, riffing on the classic Saul Steinberg New Yorker magazine cover. Instead of the Big Apple, Moseley was at the core of things; even King's Heath barely got a mention. It was fantastic. Hunt did us proud.
And all the posters were stolen within days.
The same has been happening with Lewes' work. It's led to some interesting discussions about creativity and context.
