Boznańska's art was greatly influenced by the refined paintings of James McNeill Whistler and the free way of painting by Edouard Manet and Wilhelm Leibl, artists combining realism with impressionism. During her Munich period she made large-format full-length portraits (Portrait of a Boy in a Gymnasium Uniform, ca.1890; In the Conservatory, 1890). It was then that she defined the range of her palette, narrowing it down to dark colors dominated by browns, greens, grays and black, with white and pink serving as counterpoints. Her themes included still lifes and interiors, an odd landscape and – predominantly – portraits, many of them true masterpieces. The original portrait formula developed by Boznańska and revealing the influence of Whistler's intimate portraits falls within the expressive modernist portrait trend (Girl With Chrysanthemums, 1894)....
