Friedensreich Regentag Dunkelbunt Hundertwasser (1928 - 2000) was an Austrian-born artist and architect, as well as an environmental activist. He believed that the reconciliation of man with nature was necessary in order to regain the freedom of individual creativity and expressed this vision through his art and architecture. His work is characterized by undulating curves, organic shapes and bright colors. He abhorred the square.

Hundertwasser has a unique approach to his printmaking. He is interested to explore all the various combinations of color and foil stamping rather than to select one approach for any given image. The editions seem large but the impressions sharing the same color and foil combination are only a small fraction of the total edition. The artist also incorporates the traditional printer guide in the margin of the sheet next to the image, normally cropped off when the printing is complete, as another area for exploration.
