Did the piece ever hit paper? Was it ever something that could be picked up? That's what this category is for. Advertisements, brochures, billboards, marketing collateral, CDs, t-shirts, signage... this is when I (or designers in general) go on and on reminiscing on things we've worked on. What we're trying to say, is that we can do anything. But more than that, we can help you come up with new ideas, concepts and strategy. This isn't a stretch, it's part of what designers, "real designers" do.
