Paint the change is a global street art project for social justice. They believe that public art can play a powerful role in stimulating discussions around urgent social issues. They say that a mural is not just a work of art: it becomes a social and digital event and a focus for dialogue and progress.

Paint the Change have produced a four-storey crowdsourced mural (the largest mural in London) to celebrating the NHS. Titled 200 Nationalities, One NHS, the giant artwork by award-winning street artist ATMA celebrates the diversity of the NHS and frontline workers and features a portrait of a young Londoner, an NHS health worker and hundreds of hand-drawn flowers crowdsourced from across the United Kingdom.
