Two Women Lounging on Sofa 

This is a pencil sketch by American artist Mark Rothko, known for his abstract expressionist work, depicting two women on a sofa. The quick sketch is executed in a loose and gestural style, typical of Rothko's early works, before he developed his signature color-field paintings. It's unclear whether this study is a preliminary sketch for a larger work or just an informal moment of artistic exploration. The artist's distinctive use of line and shading gives a sense of immediacy and informality to the composition.
