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.
