On a Balcony Mary Stevenson Cassatt (1844-1926)

The picture has something of this: child, artistic, Impressionism, creativity, fun, messy, palette, brush, gouache, pastel, paper, vintage, painter, portrait, summer.
Perhaps it’s a painting of a woman sitting in a chair reading a book in front of a bouquet of flowers and a vase with pink and white flowers in the background.
