Controversial Austrian artist (1928-2000) best known for his fanciful architectural designs. Two items: an official Geneve FDC with "Human Rights, United Nations" stamps and postmarks, signed in black felt tip by Friedensreich Hundertwasser; and a color glossy 7.25 x 5 photo of Hundertwasser seated outside, signed in black felt tip. In overall fine condition, with poor contrast to end of the signature on the photo due to reduced ink flow.
