Using red acetate (or just the red side of 3-d glasses) to look through, the viewer is to see two views of the censorship in this world. The viewer first sees the poster without the red acetate to see reality, and once the poster is seen through the red acetate, components in the poster disappear and a more hopeful image is shown. Since you probably won't have red acetate on hand I will show what the image will look like with and without the acetate.
