Lik's press release does give the name of a lawyer you can contact for evidence of the sale.
This doesn't mean that it's not just a $10m cash infusion from an investor in Peter Lik Incorporated who has chosen to structure his investment in the business as involving some unique prints in order to do some marketing.
That's idle speculation from me. But it both fits the skimpy known facts, and illustrates that middle ground could in theory exist. A real buyer, real money, and yet still a marketing gimmick.
For example.
