On Sept. 28, 1918, Theodore Roosevelt is the principal speaker at the opening of the fourth Liberty Loan campaign in Oriole Baseball Park, Baltimore, Maryland. Wearing a mourning armband for his son, Quentin, Roosevelt walks across the field with Liberty Loan officials, including a man who appears to be Phillips L. Goldsborough, chairman of the Liberty Loan Committee for Maryland and former governor of the state. Roosevelt pauses and speaks with Cardinal James Gibbons. On the speaker's platform, Roosevelt is cheered by the crowd. Among the notables behind him on the platform are Cardinal Gibbons, a man who appears to be Governor Emerson C. Harrington of Maryland, Mrs. Thomas J. Preston, who was the wife of former President Grover Cleveland, and her husband, Dr. Thomas J. Preston, with the dark mustache. Roosevelt addresses the crowd. There are long and close-up shots of the crowd.
