(see above), a black man is depicted lounging idly in the foreground as one white man ploughs his field and another chops wood. Accompanying labels are: "In the sweat of thy face shalt thou eat thy bread", and "The white man must work to keep his children and pay his taxes." The black man wonders, "Whar is de use for me to work as long as dey make dese appropriations." Above in a cloud is an image of the "Freedman's Bureau! Negro Estimate of Freedom!" The bureau is pictured as a large domed building resembling the U.S. Capitol and is inscribed "Freedom and No Work".
