7,400 bananas and glue

Sagmeister used green bananas to write the title into the piece, and yellow ripe bananas as the background. The strange thing about this installation is that it changed over time. As the bananas continued to ripen, the motto disappeared and the background became brownish-yellow. The whole display gradually decayed over the 24 days of the exhibition.
