The document provides guidance on design elements for posters promoting a park regeneration campaign. It recommends using bright colors and cartoon styles to attract children and families. Specific elements like logos, contact information, and images of ideal parks should promote the brand identity while clearly communicating the campaign's purpose of encouraging community involvement to regenerate local parks. Emotive language like "save" and images of happy children are meant to compel the audience to get involved and help keep parks vital for childhood.
