Lee Ufan's Relatum installation at Guggenheim involved breaking glass during 2011 exhibition setup

During preparations for his 2011 solo exhibition at the Solomon R. Guggenheim Museum in New York, artist Lee Ufan broke glass as part of installing his work Relatum. This piece, originally created in 1968 and reworked in 2011, was previously known as Phenomena and Perception B. The exhibition Lee Ufan: Marking Infinity opened in June 2011 at the iconic Frank Lloyd Wright-designed museum. Photographer David Heald documented the installation process, capturing the moment of glass breaking. The Solomon R. Guggenheim Foundation holds copyright to the photographic record. This installation activity occurred specifically in June 2011 during the exhibition's installation phase. The artwork's dual dating (1968/2011) indicates both its original creation and contemporary reworking. The exhibition represented a significant presentation of Ufan's work in a major New York institution.
