Interior decorator Bruce Buttfield (1897-1969) made his mark in the 1930s by creating distinctive furniture and rooms. In 1931, he designed the interior of the original Whitney Museum building on Eighth Street in New York City. The collection includes photographs and color renderings of Buttfield interiors.

After graduating from the New York School of Fine and Applied Art (later, Parsons School of Design) in 1936, Eleanor Horst (1892-1995) led a long career as an interior decorator. The collection includes photographs and slides of Horst projects, as well as numerous renderings of Horst designs, several by fellow Parsons graduate Lyman Martin.

Elizabeth Geary Hoopes Krusen (1908-2006) was a student and instructor at the New York School of Fine and Applied Art (later, Parsons School of Design). She specialized in watercolor interior design renderings. The collection consists of four renderings of residential interiors by Hoopes, two of which were commissioned by McMillen, Inc.
