The Chamber photographs series contains ten subseries: Annual Meetings; Arch Booth files; Chair trips, events and albums; Chamber President’s portraits and press photographs; Chamber staff and board members; Meetings and events; People and portraits; Posters; Subject files; and Washington D.C. area and Chamber Building.

The Annual Meeting subseries is arranged chronologically and dates from 1946 through 1979. Photographs were taken at the Annual Meeting and document the four-day conferences that took place at headquarters and surrounding hotels. The meeting consisted of a variety of panels, speakers, breakfasts, luncheons and dinners focusing on business issues such as taxation, private pensions, energy, labor, strikes, and education.

Three large general sessions occurred throughout the four days. The First General Session typically began with a Marine Band and flag ceremony. These three sessions had notable keynote speakers, often U.S. Presidents or Vice Presidents.

The Annual Dinners were black-tie affairs, which also had notable keynote speakers and entertainment (e.g. singers and musicians). Other sessions were panels or forums with multiple presenters and appeared to run concurrently with other events. Breakfasts and luncheons were also themed sessions with speakers.

The Chamber Board met at the Annual Meeting, and the outgoing chairman ceremoniously passed the gavel to the incoming chairman. Awards and recognitions were presented, and photographers documented the meeting. These images were then used in various Chamber publications such as Business Action, Washington Report and the Chamber’s Annual Report.

Arch Booth files contain photographs primarily of Arch Booth at Annual Meetings and other USCC events, trips and functions. The subseries is arranged chronologically and dates from 1953 to 1975.

Chair trips, events and albums subseries contains photographs of the board chair’s travels to state and foreign chambers in 1985 and from 1997 to 2011. The materials are arranged chronologically by chairman and by trip or event. A bulk of the images are from Chairman Bill Little's and Chairman Steve Van Andel’s trips. At the end of the Chair’s tenure, a leather-bound presentation album was produced documenting the year in office. The albums contain digitally printed photo-collaged pages, which use photographs and documents to depict the chair’s accomplishments. These albums date from 2001 to 2009.

The Chamber President's portraits and press photographs subseries contains images of every Chamber president from 1912 through to 1997. For some presidents, there is only a portrait photograph; however, for many, there are a number of images at various events or other press photography shoots involving the president’s spouse or family. Except for photographs of Arch Booth, which document his career with the Chamber prior to becoming Chamber president in 1974, most images of the presidents seem to have been taken while in office.

Chamber staff and board members subseries is arranged alphabetically by last name. The materials are primarily formal portraits and headshots; some are group photographs or slightly more candid. Although the images date from 1944 to 2005, the bulk of the photographs are from the 1970s and 1980s.

Meetings and events subseries contains photographs taken at a variety of Chamber occasions including press conferences, staff meetings, board and committee meetings, conferences like the Business Outlook Conference and the Aircade, as well as visits from U.S. Presidents Eisenhower and Reagan. The photographs in this series date from 1945 to 1980.

People and portraits subseries contains photographs of prominent business leaders, U.S. Presidents, foreign business and political leaders and celebrities. This subseries is arranged alphabetically by last name and dates from 1944 to 1999, with a bulk of the materials dating from the 1950s and 1960s.

Posters subseries contains large images mounted on foam core or board, which appear to have been on display at the Chamber at some point. The images are of various members of Congress, portraits of businesspeople, and other industry leaders speaking at the Chamber. These posters are dated 2000 to 2003, although at least two contain historical b&w images.

Subject files subseries contains photograph files that presumably belonged to the secretary or assistant to Arch Booth. The files primary arranged chronologically, then alphabetically. The files date from 1961 to 1975, with the bulk of photographs from 1968 to 1973. The images are generally committee meetings, organizational events, conferences, and people giving testimony.

Washington D.C. area and Chamber Building subseries includes construction, interiors, exteriors and detail images of the USCC headquarters from its first construction through to the twenty-first century. There are also numerous images of views around Washington D.C. including the Capitol Building, Supreme Court Building, monuments and statues. These images date from circa 1920 to 2003, with a bulk of the materials from 1925 through the 1960s.
