The subseries consists of commissioned commercial photography (portraits, candids, aerials) carried out primarily by three firms (Aero Surveys Ltd., ca. 1948 to 1958; Jennings Ltd. Photography, ca. 1971 to 1974; and Hans Giesen of British Columbia Ltd. ca.1973). None of these firms have a current detectable presence. Other commercial photographers include Jack Cash Photographic Studio, Pope's Studio, Paul Ponich, Kermode Studio, and Ribelin Photography. Of these, only Pope's Studio is clearly still extant. Other photographs originate from the mill(s) proper, and yet others have been collected from third parties' personal photo collections (acquired or copcopied) by Sharron J. Simpson. There are a total of approximately 2,350 images in the form of photographs, scans & photocopies on paper, slide transparencies, negatives, and contact prints documenting mill business (under various nomenclature and ownership) during the years ca. 1910 to 1994, in colour and black & white, with sizes ranging from oversize posters to 10x12cm prints.
