The Dorothy Elizabeth (Baker) Bond World War I Poster Collection consists of 247 illustrated posters and broadsides that Bond collected during her work selling war bonds. The posters, which date from 1914-1919, were produced by various government agencies and non-profit organizations to promote military enlistment, fundraising campaigns, and homefront efforts supporting of the war. In addition, there are a few photographs related to Bond's work and her family's involvement in the war effort. The collection is organized into two series, Posters and Photographs, with the Posters series being subdivided by the organizations that published the posters.

Series I. Posters contains 247 individual posters of 185 designs that were created by a variety of organizations to support the war effort.

The largest grouping of posters, with a total of 60, were used to promote financial support of the war. These posters advertise the purchase of liberty bonds, liberty loans and war savings stamps. Four liberty loan campaigns, which spanned April 1917 to September 1918, are represented along with the victory loan campaign of April 1919. These posters have a variety of styles and messaging. Some appeal to people's sense of patriotism with images of Lady Liberty, former presidents, and the American flag. Some appeal to women's and motherss sense of care for their sons abroad. A few posters are aimed at children to convince their parents to buy loans. Some poster designs use fear tactics with graphic scenes of war. Joan of Arc is evoked in a few posters to inspire citizens to help save their soldiers and war victims in the way Joan helped saved the people of France.

The War Bonds and Liberty Loans subseries of posters is the only grouping in the collection with posters that relate to aviation. A poster titled "Shall we be more tender with our dollars..." from the Second Liberty Loan campaign, a poster titled "My Soldier, Buy United States Government Bonds" from the Third Liberty Loan campaign, a poster titled "Provide the Sinews of War Buy Liberty Bonds" from the Fourth Liberty Loan Campaign, and a poster titled "That Liberty Shall Not Perish from the Earth" also printed for the Fourth Liberty Loan all have airplanes in their illustrations. One poster titled "Victory Loan Flyers watch for the Airplane Special" from the final Victory Loan campaign refers to aviation most directly.

A total of 44 posters campaign for humanitarian causes. The American Committee for Relief in the Near East, an organization founded to raise money for response to the Armenian and Assyrian genocides in the 1910s, has six posters in the collection, all appealing for monetary donations to support their work. The American Red Cross's work has significant representation with 38 different posters. The majority of these call for donations to support their nursing program; some are recruiting posters for nurses; and some are posters for members to hang in home or business windows to show their participation. There are a few variants of the "Greatest Mother in the World" theme symbolizing the caring and nurturing qualities of the organization. A few of the Red Cross posters are also Christmas-themed, building off of the giving spirit of that season.

Recruitment of men to serve in various military branches is represented with 43 posters. Fourteen are for the Army, 13 are for the Navy and 10 are for the Marines. Two of the Naval recruitment posters include imagery of girls or women in sailor's uniforms. Many of the posters, especially the Naval and Marines ones, have location information for recruitment centers in Seattle, Washington stamped or printed onto them. None of the recruitment posters are specific to aviators, as the U.S. Air Force had not yet been formed. Six posters are British and Canadian military recruitment posters. These seem specifically aimed and British and Canadian citizens living in the U.S.

Numerous ways that people in the U.S. could support the homefront effort are illustrated through a variety of designs. Twenty-three posters published by the United States Food Administration advertise and explain how people could use food efficiently to ensure enough was available to send to troops abroad. One poster for the Y.M.C.A. encourages support for its organization to help support soldiers fighting. Four posters published by the United War Work campaign encourage support of some of their member organizations, such as the American Library Association, Jewish Welfare Board, Salvation Army, and Y.M.C.A., and their efforts to support soldiers. Some other assorted posters include one encouraging book donations for soldiers and another advertising a women's parade in Seattle.

While the majority of the posters are designs that would have been seen in the U.S., there are also ten French posters present that Bond's brother Les collected for her while he was serving abroad. These primarily are in support of French fundraising efforts but one advertises the American Red Cross and one celebrates a victory of French soldiers in Strasbourg, France.

Across all the groups of posters, there are at least 72 artists and illustrators represented, though many illustrations are uncredited. Most artists are represented with just one poster, but some artists have several designs present, including Howard Chandler Christy, Abel Faivre, Charles Buckles Falls, Harrison Fisher, James Montgomery Flagg, Alonzo Earl Foringer, Henry Raleigh, and Sidney H. Riesenberg. Women artists with work in the collection include Ethel Franklin Betts, Eugenie De Land, Frances Adams Halstead, and Anna Milo Upjohn.

Some additional pieces of ephemera, including newspaper clippings with illustrations and a map, are at the end of the series and provide additional examples of wartime propaganda.

Note that some of the posters depict wartime violence and use outdated derogatory language. Some of this language exists in the poster titles given in the inventory.

Series II. Photographs, is a much smaller component of the collection comprised of 29 black-and-white photographic prints. Some of the images depict members of Bond's family including portraits of Bond; the Baker siblings together; an image of Bond's brother Leslie "Les" D. Baker and her husband Elmer Cadwell Calhoun when they met up in France; and an individual portrait of Elmer. In addition to selling war bonds, Bond participated in the First Girl Cadets of Washington in support of the war effort, and eight photographs depict parades and members of this organization. Also present are 15 photos of various soldiers that Bond met in Seattle, Washington during her work selling war bonds. Of particular note are a few photos of British soldiers in front of a British recruiting office. Posters represented in the collection are seen through the storefront windows behind the soldiers in the photos.
