Put earlier works above later ones. Changes may be visible in later works due to experiments or experiences the artists have incorporated. Preservation, presentation and promotion. Preservation begins as soon as an artwork is completed. Know the optimum ranges for exposure to lighting, and the preferred ratio of temperature and humidity.
Presentation is concerned with the showing of artworks.
Talk to the organisers of a school art exhibition or pretend you have been asked to arrange one. Think about backgrounds, lighting, crowd flow, security, insurance. Promotion comes next. Publicity for large public galleries may include sponsorship by big companies, television, newspaper and magazine articles as well as radio advertisements. For a school, you may use a photo in the school magazine, dodgers in letterboxes and shop windows and a mention on access radio.
