The Joset Walker collection consists of the contents of two scrapbooks kept by Walker. While largely consisting of news and magazine clippings of advertisements for Walker's designs in the 1940s and '50s, the scrapbooks also include photographs of actresses and models wearing Walker's designs, department store window displays, publicity materials, and biographical clippings about the designer.

Scrapbook 1 covers the years 1932 through 1936, documenting Walker's costume design work for RKO Pictures, with costume stills of Danish-born actress Gwili Andre (autographed), Irene Dunne, Constance Bennett, and Katharine Hepburn in Walker's costumes for Hepburn's film debut, "Bill of Divorcement," as well as photographs of Walker alone and at work with colleague Kate Lawson in RKO's wardrobe department. Some of the RKO photographs are by Ernest A. Bachrach. Also included in this scrapbook are clippings advertising Walker's early activewear for women, which feature models engaged in activities such as hunting, archery, boating, and tennis (Walker designed a line of tennis wear for Amelia Earhart); and several programs for events featuring Walker's designs.

Scrapbook 2 consists predominantly of department store advertisements for Walker's activewear designs clipped from regional newspapers, as well as fashion features from national magazines such as Harper's Bazaar, Life, Mademoiselle, and Vogue. The scrapbook also includes merchandise reports from the Retail News Bureau and print promotional materials from textile manufacturers. While most of the scrapbook covers the years 1952 through 1955, clippings from the 1940s are found in the second half of the scrapbook, as well as biographical clippings about Walker dating from the 1960s through the '80s.

The scrapbooks have been dismantled, and certain materials, including all photographs, are housed separately from the scrapbook pages. The scrapbooks do not contain materials pre-dating Walker's work for RKO in 1932, with the exception of an advertisement for the Stern Brothers department store bridal department.

While all of the materials in the collection deal with Walker's professional career, a small number of clippings document her life in the 1950s and afterwards. Of note is a complete sample issue of a magazine, Suburbia Today, featuring an interview that profiles Joset Walker's efforts to design for the American suburban housewife.
