In the final decade of his life, the work of Louis Icart moved more into an impressionist style. By playing with colors and light his style expanded into new areas. He also continued to produce occasional works that could be classified as boudoir art although there was little market for it. Boudoir art had long passed it’s zenith by 1940. Due to the shortage of copper for plates during World War II, he spent much of his artistic energy on oil paintings. The majority of his etchings graced limited edition books and collections. He continued to produce both oils and etchings until his death in 1950. It is difficult to find works from this period. With low production and small edition sizes they rarely come to market. The value of these works continues to increase.
