In addition to identified work there are unidentified fashion illustrations. These could be by Roy Little, Robert Galster or Gilbert Ireland, all of whom have fashion illustration work in the collection, but there is no signature on these drawings and no distinguishable way of attributing them. Additionally, slides of photographs from a fashion shoot contain no identifying or contextual information. They are estimated, based on the use of Kodachrome slide film, to be from the 1960s or 1970s.
