Man Leaning Back and to the Left, Right Hand Raised to Mouth 

This pencil sketch by Mark Rothko, "Man Leaning Back and to the Left, Right Hand Raised to Mouth", depicts a figure in a reclining pose. Rothko, known for his abstract color-field paintings, was also a skilled draftsman. The loose and gestural lines in this sketch, likely a study for a larger work, capture the essence of human form in a simplified manner. The figure's posture conveys a sense of contemplation or introspection, characteristics that would later inform Rothko's abstract works.
