Pages Bigger Than Their Books

Double page spreads can be folded out to two or three (or more) times their bound size, resulting in hidden portions of a larger overall illustration. The pages can be unfolded to reveal the illustration underneath. The proportions bring to mind height, or depth. If there are multiple bits to unfold, it could work somewhat like a piece of paper-mation. The first illustration is hidden completely with the first unfolding, revealing a second. Half of that illustration is hidden with the next unfolding, revealing more. A third of that illustration is hidden, and double that size revealed with another unfolding, and so on. Could be great for something flying or sinking.
