The New York City Panorama was featured in two 2011 fictional works: the movie New Year's Eve directed by Garry Marshall, and the book Wonderstruck by Brian Selznick. Each year, the Queens Museum hosts the "Panorama Challenge", a trivia contest run by The City Reliquary. Contestants use the Panorama to identify various New York City landmarks. A scale model of the 1964 New York World's Fair site, showing all the buildings and pavilions of the time, is located in a separate area devoted to World's Fair exhibits. Relief Map of the New York City Water Supply System For the 1939 World's Fair, city agencies were invited to produce exhibits for the New York City Pavilion. The Department of Water Supply, Gas and Electricity (a New York City Department of Environmental Protection predecessor agency) commissioned the Cartographic Survey Force of the Works Progress Administration to create the large Relief Map of the New York City Water Supply System and watershed. Work began in 1938, and a team of map builders toiled over the map with an immense depression-era budget of $100,000 (). At , the map was too big for the allocated space in the New York City pavilion, resulting in its elimination from the World's Fair. Ten years later, the map made its first and only public debut at the city's Golden Anniversary Exposition in Manhattan's Grand Central Palace. By the start of the 21st century, the 27-piece map in storage was in desperate need of conservation. In October 2006, the New York City Department of Environmental Protection and the Queens Museum sent the historic display to McKay Lodge Fine Arts Conservation Lab in Oberlin, Ohio, for restoration. Over the next 18 months, conservators and technicians worked on the model full-time, removing over 70 years of accumulated dirt and re-paintings. Clearing away the dirt and debris, they found much of the original geography and painted details to be intact or recoverable. Road maps and satellite images were used to restore lost portions of the model. Near the 70th anniversary of the model and the 100th anniversary of the inauguration of the Catskill System's construction, the map was restored to its original form and was installed in the former New York City Building (now the Queens Museum), where it remains on long-term loan.
