The photographs in Folders 1 through 15 and all associated rights, including copyright, were transferred to Brooklyn Historical Society in 2008 by Heather L. Nesle, Vice President of Community and Philanthropic Services, HSBC Bank USA, N.A.
The provenance and source of acquisition of photographs in Folder 16 is unknown. The lack of documentation about them when the bulk of the collection was donated by HSBC Bank in 2006 indicates that they were not part of that accession, but were subsequently added to the collection artificially.
