...the yes is history...John walked into Indica Gallery show in London in 1966. The exhibition title, YES YOKO ONO, refers to the interactive installation known as Ceiling Painting, an important work shown at Onos historic 1966 Indica Gallery show in London. The viewer is invited to climb a white ladder, at the top of which a magnifying glass, attached by a chain, hangs from a frame on the ceiling. The viewer uses the reading glass to discover a block-letter instruction beneath the framed sheet of glass — it says Y E S. It was through this work that Ono met her future husband and longtime collaborator, John Lennon.
