Gustav Klimt The Sunflower note card. Oil painting on canvas from 1907. Austrian artist Gustav Klimt is most recognized for the portrait work he completed during his golden period, however he also painted some beautiful garden and landscape paintings. Sunflower is arguably his most famous flower painting. A large sunflower bends towards a green field full of other colorful flowers under the weight of its heavy blossom. A great gift for fans of Gustav Klimt, sunflowers, Austrian symbolism, and art nouveau.
