What I still don't understand is how it even matters. Even if AA made the negatives, there are no "original" prints. Any new print you buy, obviously not made by AA or even by any of his assistants under his supervision, is worth nothing more than a print by whoever is currently printing these things. Regardless of whether or not they are AA's negatives, why would anyone have paid hundreds or thousands of dollars for these new prints? They should have been $12.50 either way.
Even if the negatives had been without a doubt Adams', authenticated numerous ways and admitted to by the Adams Trust, possessing them does not give the possessor copyright, with the right to produce and sell prints.
How Norsigian's lawyer (gee, haven't heard from him in a long time, have we) thought he could get around that one while making money off them...sheesh. "...matter of significant public concern."-yeah, right!
Relatively few of Adams' images have been seen. What would make any of these supposedly "lost" (abandoned, whatever) images worth more than any of the thousands in the archive in Tucson? It was nonsense to begin with.
