Surprising news arrived today. The discovery of human remains from the Wounded Knee Massacre aftermath restoration has been incorporated into the official program notes of an exhibit at the Montreal Museum of Fine Arts, item number 76. The Library of Congress also credits me in its updated bibliographic record. The museum is exhibiting an unedited version of the image; possibly the presence of the bodies was a factor in its selection.
The individual who shared the news does not appear to have a connection to the museum. Would love to make contact with Quebecois Wikimedians who could follow up on this and establish ties with the museum.
