What is a scamp in design?
It's a sketch of an idea, and represents how the concept works. What's great about the scamp is it allows ideas to be worked on and presented without having the feel of a final design piece. It doesn't display typefaces, photography style or written copy, it purely displays 'the idea'.
What is a scamp in advertising?
It may mean different things to different people, but to me a scamp is a rough, a sketch, a hand drawn mock-up of an advertising concept. It will contain the visual idea and message which make up the ad concept, the art and copy. They're deceptively simple.
