1) This document is a picture of a jazz band. The picture is in black and white and we see seven people, one woman and six men. I can see different instruments too, like a piano or a percussion section.
2) I think the atmosphere is happy and the sound really lively.
3) I can guess this group has popular at the Roaring Twenties, after the world war 1 and during The interwar period of wars.
J’espère que cela t’aidera !
