I Pledge by William Harroff is a snowglobe bookwork with words from the pledge of allegiance printed on pieces of plastic taking the place of snow. The plastic bits are floating in a glycerin solution inside a plastic globe. In this case, the ongoing stability of the plastics and the glycerin solution are of concern, as is the integrity of the seal holding the liquid in the globe. Since its creation in 1994, the interior plastic pieces seem to be yellowing and it appears that the liquid levels in the globe have decreased.
