(20th century) American Illustrator.
Little is known about Ruth Eastman, who carved out a short successful career doing advertising work and cover illustrations for the publications shown here (McCall's and Today's Housewife) as well as House and Garden, Liberty and the humor magazine Judge. Her stylish depictions of similarly stylish young women relied upon a sure-handed use of shape and color grounded in art nouveau.
Her sense of design comes through most strongly on her advertising work for Murad Turkish Cigarettes, United Cigar Stores, and Jantzen swimwear.
Eastman was active between 1915 to 1930 or so, after which she seems to have disappeared from the industry.
