Milan has captured the attention of the world as the site of its Expo from May 1 to October 31. This is the first such fair to have a specific theme — "Feeding the Planet, Energy for Life" — that looks to the future of sustainability in the context of taste, health, culture and pleasure.

Fred Plotkin, world-renowned expert on everything Italian, spoke at the Expo on its opening weekend and will come to Washington to describe to Americans the great variety of offerings at the Expo as well as the American role in it.
