At the time of completion, the mural by Thierry Noir was the tallest in the UK. Titled ‘A message to the Children of London. Brush your Teeth, at least, three times a day‘ but also dubbed ‘The Acton Giant‘ stood at 38.2 metres (125 feet) and 14 storeys tall. The mural on Barwick House on the South Acton Estate in London was created in association with Artification, a London-based arts charity, as part of its public art programme to beautify the South Acton Estate.
