The crowd, dissolving backward
The whole upper register, behind the bench
Behind the front three, rows of anonymous passengers — men in tall hats and caps, women in bonnets — recede into the dim car, and the farther back they go the sketchier and more ghostly the faces become (the unfinished paint exaggerates it). Nobody back there is an individual; they are the crowd, the mass of the modern city packed into a moving box.
