In this artwork, how is the Description discussed?
The Third-Class Carriage evidences Daumier's interest, as also seen in his graphic works, in the lives of working-class Parisians.  Third-class railway carriages were cramped, dirty, open compartments with hard wooden benches, filled with those who could not afford second or first-class tickets. 
The versions in New York and Ottawa are both in oils on canvas, and measure 65.4 cm × 90.2 cm (25.7 in × 35.5 in).  On the wooden bench seat facing the viewer are seated, from left, a woman nursing her baby, an older woman with her hands clasped atop a basket, and a young boy asleep.  The figures may be intended to peasants, influenced by Jean-François Millet.  Seated behind them are anonymous rows of men and women.
