What I would do is offer a reprint to anyone willing to send the original back. So, give people a month to request it or something, send those people a tube to send the original back in, then know exactly how many to reprint. Then, resell the originals with the typos that are returned as a novelty. I know I'd be happy to purchase one of these typo-ed ones, which I'd hang in my apartment and love to tell the story about.
