We have provided a date of 1977 to indicate when it was completed, although the imagery and assemblage may well have begun much earlier.

In his collage work, Henderson assembles fragments of image and text in order to activate them in new ways. He wrote: ‘I want to release an energy of image from trivial data. I feel happiest among discarded things … fragments cast casually from life, with the fizz of vitality still about them.’

Henderson created the collages in this room between the late 1940s and the end of the 1970s. They bring visual scraps of modern British life into dialogue with imagery from other places and periods. His intricately layered collages reflect on the passing of time. They dwell on natural decay, the ruins of war, and the crumbling of empires. They also engage with the visual culture of their own time and cast a critical eye across contemporary images intended to stimulate aspiration, consumption and desire.

Henderson was aware of the historical legacies of collage. His work references the Victorian hobby of ‘découpage’, decorating objects with paper cut-outs. The subversive collages of Dada and Surrealist artists in the early 20th century provided him with other important precedents. At the same time, his work engages with more recent artistic developments, including the rough textures of brutalism and the bold graphics of pop art.

Henderson’s creative practice spanned fine art, photography, exhibition-making and interior design. Collage was always at centre of his thinking. As one critic observed, ‘Whether the medium is man, nature, time, weather, or even words, the underlying idea of this artist’s vision is that of collage.’
