Among the artists who were friends of Otto Antoine were several other “postal painters,” such as Richard Albitz (1876-1954) and Gustav Fenkohl (1872-1950), who had evolved from Berlin’s art scene. All his life, Otto Antoine was loyal to impressionism. His style barely changed after his training under Skarbina, not even when an “art revolution” occurred in Berlin in 1905 introducing expressionism in lieu of impressionism.
