Museum of Moden Art (MOMA) Curator Sarah Suzuki describes it as follows:
If you ask 100 art-world types "Who is Kingelez?" 95 would say "I have never heard of him", and 5 would say "He is my favorite artist."
Bodys Isek Kingelez was (he died 2015) an artist who used everyday material like paper, toothpicks and plastic bottles, to create his cityscapes.
The piece of art you saw in the Beauty of Art XX was U.N.
Kingelez was born in the Democratic Republic of Congo, 1948. He became a teacher before he became an artist.
An interesting anecdote about his early steps as an artist, was when he presented a paper sculpture to museum officials. When seeing the technical mastery of the creation, they didn't believe this unknown man had created it. They even accused him of stealing it! When he created another one before their eyes, they finally believed him and hired him as a restorer.
He called himself a designer, an architect, a sculptor, an engineer and an artist.
His art is colourful and filled with joy. Many say that this art makes them happy.
You say it is colourful and weird.
