I once tracked an item as it got sold and re-sold on E-Bay over the course of a year. It was an unusual item, so it was easy to identify when it popped up again. The first seller gave it a "bare bones" description and one or two fuzzy pictures. He sold it for about two hundred bucks.

Over the course of a year, it would get re-sold about once every month or two. Each time, the description got more flowerly and elaborate. The photos can sharper and larger. Eventually it became a "rare, and historic collector's item", fully restored after much painstaking labor by experts (that owner had it about two weeks). After it became "rare, and historic", it finally sold for about $2,000.

Isn't E-Bay fun?
