acqinfo: label: Provenance
content: Bridges is a portion of the Business Ephemera Series of the Warshaw Collection of Business Americana, Accession AC0060 purchased from Isadore Warshaw in 1967. Warshaw continued to accumulate similar material until his death, which was donated in 1971 by his widow, Augusta. For a period after acquisition, related materials from other sources (of mixed provenance) were added to the collection so there may be content produced or published after Warshaw's death in 1969. This practice has since ceased.

processinfo: label: Processing Information
content: In 2016, with funding provided by the Smithsonian Institution's Collections Care and Preservation Fund, the Archives Center at the National Museum of American History implemented the use of minimal level processing standards to increase information about and facilitate access to more of our collections. 
            
A large portion of stored material from the original acquisition received minimal level processing, which resulted in additions to this Subject category. This effort included basic arrangement and replacement of non-archival housing for long-term stability, but staples and other fasteners have not all been removed. Revisions to the encoded finding aid were made to reflect the added content in context to the previously processed material.

Minimal level processing and enhancement of the machine-readable finding aid completed by Nicole Blechynden, September 2017.
