I can't remember a time where there was a reversal in cover cleaned books. This may be the first I've seen. Usually cover cleaned books are irreversible, unless it was dry cleaned but the label didn't state that. Reinforcement to my knowledge would be a problem to remove because the cover could be loose or possibly detached. It was gutsy for the person who did the resto. removal, and if it were me, I'd leave it alone. But anyways, there is a bad stigma with this book now that the full history is shown.
