The Kiss by Gustav Klimt.
The most famous artist of the Art Nouveau period is Klimt who sense of decoration and design made his artwork rich and complicated. The two figures seem to emerge from the field of gold, flowers and shapes.
Pink Flamingos
Flamingoes by Sydney Long, c. 1905-06, The National Gallery of Australia
Long's work was often controversial because of the subject matter he chose to portray in his languid art nouveau style. He was fond of nudes and tranquil scenes. He often chose flamingos as a subject matter and this is perhaps his most stylistic version of the subject matter, where colors and curves become the focus rather than a realistic portrayal. After 1918 he concentrated on print making translating many of his most popular paintings into prints.
