20 years later, however, the artwork was partially soiled and smeared, so that the friendly effect subsided. Kuhna himself suggested replacing the acrylic paints with tile ceramics in order to prevent vandalism in the future. In just six weeks, “Rivertime” 2017 was restored according to this new idea. Shortly thereafter, the artist died. His work will live on for a long time and now shines twice as beautifully with the ceramic sheen of the tiles.
