The image seen above comes from Print's Regional Design Annual 1989
One of the words that the textbook used to describe unity and variety was "lively" and that's exactly what comes to mind when I look at this ad. Something about the layout of this ad seemed really different to me. It was cluttered, yet, I really liked looking at it. This image has so much variety and different things to look at. None of the items technically should go together, but since they are matching up the colors and they have that pastelly (I know that's not a word but I'm going to invent it for that particular sentence) vibe to them everything fits really well.
