Artist's renderings and photographs depicting parade floats designed from the 1930s to the 1950s by floral designer Malcolm P. Hutchinson (1899-1978) of Portland, Oregon. Most of the floats represented were designed for the Portland Rose Festival. Hutchinson worked for florist Tommy Luke until 1951, when he left to focus on the Hutchinson School of Floral Design, which he had founded in the 1940s.

Collection includes two color prints by Eric Gustavus Michelson. The prints are artist's renderings made for the U.S. Army Corps of Engineers, one depicting an aerial view of The Dalles Dam and the Columbia River, and one showing a sectional view of the powerhouse of the McNary Dam.
