@nhbenz is correct. It’s a print from one of Maud Tousey Fangel’s commercial illustrations, circa 1940s-1950s. She was born in 1881 and died in 1968.
From the 1930s through to the 1950s, if you saw sketch or portrait of a small child on the cover of a women’s magazine or inside it advertising things like Colgate's Talc Powder, Cream of Wheat, or Squibb's Cod Liver Oil, she was almost invariably the artist. She worked mainly in pastels and lithograph prints from her work were sold in the thousands during her heyday and so have very little value. She also did commission portraits of children, notably for wealthy patrons.
