Hand-colored lithograph bird's-eye view of Commercial Avenue at the Union Stock Yards, Chicago, Illinois, showing a large flock of white sheep being driven down the central avenue by mounted drovers, with cattle pens packed with livestock filling the right foreground. Red brick commercial buildings — including Clay, Robinson & Co. — line the left. The scene conveys the massive industrial scale of what was then the world's largest meat-processing complex.
