Looking into it a bit, they seem to know they don't own any copyrights. It seems like the plan is to leverage the interest indicated by the outrageous purchase price to convince those involved to let the make the works public. On the one hand, that seems like a shaky plan at best. On the other, stranger things have happened. What they do have for sure now is attention, and attention has value. Maybe not $3 million dollars in this case, but value.
