The author of this work is Chiharu Shiota.
He has presented around the world many solo exhibitions, one of these masterpieces is "The KEY in the HAND", exhibited in the pavilion of Japan at the Venice Biennale 2015.
This photo was taken inside the pavilion. We can see an old boat in the middle of the room and above it there are a lot of keys hanging on thin red threads.
In my opinion all the keys are possible solutions to our everyday problems.
With these keys we can try to open doors and find the most suitable solutions.
