The original image BWK # 7883 ( Represents a Kilburn signature / iconic piece for the WCE. ) was published on the official card stock to be sold at the World's Columbian Exposition [ above and its reverse view ] by the B. W. Kilburn firm. There were usually several negatives taken to insure the needs of the printers. One of these images Keystone # 33148 [ below ] was later used in the Keystone list but, without photographic credit.
The negative of this view, among others of original Kilburn stereoviews, has found its way into the Keystone - Mast Collection held at the University of California, Riverside, CA.
