A woman and a baby asleep on a sofa was originally intended as a lithograph, which may have been drawn in Paris in late October or early November 1891. 1 It is dated by comparison with several lithographs including Mother and Child, No. 3 c052, Mother and Child, No. 2 c053 and Mother and Child, No. 4 c054. However, the pen drawing may have been done later (Whistler used purple ink during the period 1892-1894).
