This series consists mostly of photographs of work done by Harry Wesslund, including department store displays and exhibition booths at trade shows. The retail store displays include interior and exterior displays, as well as numerous window displays. The exhibition booth photographs cover many local companies and appear to be from trade shows across the country. The photographs are mostly undated, but appear to be from the 1940s and 1950s, with one photograph identified as 1965.

The companies that Wesslund worked with include Wurzburg's, Herpolsheimer's, WOOD Radio and TV, American Seating Co., Michigan Consolidated Gas Company and Atwood Brass Works. Graphic materials from Wurzburg's, Herpolsheimer's and WOOD may be found in Series II.
