This shows a group of men playing basketball in a back yard.
The picture is faded and also has quite a lot of marking which suggests it is probably quite old and this is somewhat borne out by the clothes the men are wearing which have the look of either the 1940s or 50s. The slide is an Ansochrome, which is an American film and basketball is a much more popular sport in America than Europe so I guess this is an American scene.
The men are obviously not dressed for sport, so it is a makeshift game and therefore I assume it is in a back yard or something similar rather than an arranged game.
