 The most successful case, I would say, is the case of the Sue specimen, which was auctioned in the United States and sort of started all of this off. McDonald's and Disney partnered with the Field Museum to buy it and put it in the Field Museum and prepare it and do a bunch of research on it. And that was absolutely the best outcome that we could ever hope for from the sale of a fossil. But that just doesn't happen very often. It's only happened once.
