After chewing the gum for about 40 years, a gum collector might find the gum wrapper useful in determining the original size, shape, flavor, and brand of the gum.
Then he could add a little of the correct color, and try to smooth it back out to its original shape.
Food for thought?
(I understand what you're saying Dave, just couldn't resist sharing this amusing thought.)
