"Costume Study" by Henri Lehmann is a graphite drawing that demonstrates the artist's technical mastery of figure drawing and drapery. The work employs stumping, a blending technique using a blunt tool, to create subtle tonal transitions and enhance the three dimensional quality of the fabric and form. As a costume study, the drawing serves as a preparatory work, likely intended to inform a larger historical or narrative painting, showcasing Lehmann's academic training and attention to authentic period detail.
