The image is a black and white photograph of a large group of people gathered on a stage. The stage is set up in front of a building with large windows. The people on the stage are dressed in formal attire, with some wearing suits and others wearing dresses. They are all holding musical instruments, including violins, cellos, and trumpets. In the center of the stage, there is a man standing at a podium and speaking into a microphone. The audience is seated in rows of chairs, facing the stage and attentively listening to the speaker. The photograph appears to be from the early 20th century.
