Bringing back to life this 5+ year quiet thread, I thought it appropriate to add a postscript.
I just finished reading a 2017 book by author and photography professor Pamela Bannos titled "Vivian Maier - A Photographer's Life and Afterlife".
It is absolutely fascinating.
Professor Bannos seems to have exhaustively researched information about Vivian Maier and her life and photography, along with the activities of Mr. Maloof, Jeffrey Goldstein and others who obtained so much of her photography.
If I understand correctly, it was as a result of Professor Bannos' research that the fate of Vivian Maier's brother was ascertained - he apparently pre-deceased Ms. Maier, having died while a resident of a psychiatric institution.
The original 5 storage lockers of her photography, documents and books were sold at auction for $260. The contents together weighed four tons!
Those contents were subsequently re-sold at auction, in various lots, the sale proceeds of which totaled to $20,000.00
The purchasers then set about spreading the contents into the hands of many, many people, including Mr. Maloof and Jeffrey Goldstein.
The historical information about Vivian Maier presents her as a much more accomplished and interesting person and photographer than Mr. Maloof's movie presents.
And it is unlikely that Mr. Maloof's choice of "heir" for the estate is the only heir.
