It is a postcard from 1904 to 1918.
The house has a house number so it must be in town. The number is 418.
There is a little boy with a gun on the left and a man with a hose spraying water on the right..and everyone else is just waiting around.
My best guess is that the man in the jacket and the lady in the hat are visiting.
Thanks for stopping by. Do come again:)
