The Rauschenberg bicycle sculpture.
We have always loved this sculpture and pass it every day when here.
From Wikipedia about this great artist:
Rauschenberg (October 22, 1925 – May 12, 2008) was an American painter
and graphic artist whose early works anticipated the pop art movement.
Rauschenberg is well known for his "Combines" of the 1950s, in which
non-traditional materials and objects were employed in innovative
combinations. Rauschenberg was both a painter and a sculptor and the
Combines are a combination of both, but he also worked with photography,
printmaking, papermaking, and performance. He was awarded the National
Medal of Arts in 1993. He became the recipient of the Leonardo da Vinci
World Award of Arts in 1995 in recognition of his more than 40 years of
Rauschenberg lived and
worked in New York City as well as on Captiva Island, Florida until his
death from heart failure on May 12, 2008.
