The "world’s fair" was a large international exhibition of a wide variety of industrial, scientific, and cultural items that are on display at a specific site for a period of time, ranging usually from three to six months. Since 1970, the world's fair has been themed, often environmental in nature, rather than a celebration of a historical anniversary or a colonial empire like the earlier fairs. Many of these modern themed world's fair were shorter festivals held in smaller cities compared to Paris, New York, Chicago, and other headliners of the early 20th century. The 1984 fair was held in New Orleans, Louisiana.

The Louisiana World Exposition's theme was "The World of Rivers—Fresh Waters as a Source of Life." The expo was plagued with attendance problems and subsequently gained the dubious distinction of being the only exposition to declare bankruptcy during its run.

The bankruptcy and bad publicity of the 1984 New Orleans World’s Fair would lead to a three decade pull back of the United States from the World's Fair landscape, with subsequent withdrawal from the Bureau of International Expositions. Although New Orleans was a success from an exhibit standpoint, unrealistic attendance estimates made the fair as a whole a failure with a low attendance of seven million. The previous world fair held in Knoxville, Tennessee drew in eleven million.

This button was created for the purpose of advertising the 2011 imperatives for the Department of Education of Iowa. It’s based on sharing the current level of academic achievement in Iowa and ideas on how to improve it. Various reports were released; one such report that was released centered on the Science, Technology, Engineering and Mathematics (STEM) Education plan. It introduced a new framework called “Response to Intervention” that it hoped to use to advance the education system in Iowa.

In 1972, Kensett Iowa celebrated its 100^th anniversary with a festival and established Centennial Park which is currently used for yearly town anniversary celebrations, and other outdoor events. Kensett is a small rural community in Worth County formed in 1872 shortly after the railroad was built through that territory. It was named after a Baltimore oyster packer named Thomas Kensett who vowed to build a church in the town if the citizens named it after him. The community was named Kensett but the town’s namesake never fulfilled his promise.

The 49th state to join the United States, Alaska was purchased from Russia on March 30, 1867 for $7.2 million (approximately two cents per acre).  Alaska's state sport is dog mushing, the state fossil is the Wooly Mammoth, and the state mineral is GOLD!

The Pacific walrus (pictured) inhabits the Bering and Chukchi seas to the west coast of Alaska.  They prefer shallow waters and eat mainly clams. The average adult male weighs over 2,700 lbs and is 10.5 feet long.  Both the male and female walrus has tusks which can reach over 3 feet in length.

Second hot air balloon has a yellow and red zig-zag design. Black text on yellow border. 

The button pictured above most likely served as a souvenir for Read-A-Million participants in a 1985 event in Iowa. The 'Read-A-Million Minutes' program was started in 1981 by Duane Boehmke, an elementary school principal from Denver, Iowa. Since then, the program has been active in Minnesota, Wisconsin, Missouri, Arizona, and Georgia. Even internationally, in such places as Japan, Saudi Arabia, and Peru. The Read-A-Million minutes program is developed and coordinated by the State Area Education Association Educational Services, with help from state educators throughout Iowa.

The button pictured above is a tourist souvenir from the Heritage Hjemkomst Interpretive Center in Moorehead, Minnesota. The Hjemkomst is a life-size replica of a Gokstad Viking ship discovered in Norway in 1881. The button commemorates Hjemkomst's successful sail from New York City to Oslo, Norway in the summer of 1982. The idea of building the Hjemkomst was that of Robert Asp, a guidance counselor who worked at Moorehead Junior High School. Although he died before the sail, the Asp family carried out Robert Asp's dream of sailing the Hjemkomst all the way to Norway.
