The Louisiana Purchase Exposition, commonly known as the Saint Louis World's Fair of 1904, was the last great international exposition before World War I. The fair, built on a 1,200 acre site, included hundreds of thousands of objects, people, animals, displays, and publications from 62 exhibiting countries and 43 of the 45 states. The setting of world records, such as the largest organ, and working displays of every important technological advance were significant design goals. The Fair was a combination of trade show, civic showpiece, and monument to culture, along with more than a tinge of American pride. The Fair showcased the grandiose ambition of the gilded age, forming a kind of collective tribute to the nineteenth century's international understanding of the furtherance of peace, prosperity, and progress. It's a grand snapshot in time of American and foreign societies as they wished to portray themselves.

Starting in the 1630's, Dutch New Amsterdam settlers tried to set their new home base across the Hudson river. Despite conflict with the native Indian Lenapes tribe, in 1660, a new town known as Bergen was settled atop the Palisade Hill . Soon, farms, religious congregations, and the self-governed communities spread throughout the region. The quiet and rural nature of Bergen survived the American Revolution, but, in 1804, a group of New Yorker investors purchased land along the waterfront for a new development which they called the Town of Jersey. Robert Fulton, an entrepreneur, soon built a dry dock and in 1812 began to run his steamboats and ferries to and from Manhattan to Newark and Philadelphia, sealing area's future as a major transportation hub, connecting the mainland United States with New York and Long Island. Access to the Pennsylvania's coal mines attracted industry which, in turn, required population growth. In the 1880's, Irish and German immigrants, fleeing their homelands, gave the area another boost. It was a melting pot of nationalities and ethnic tensions battlefield. Expansion of the railroads along the waterfront, growing industrialization and a steady supply of workers continued through the Civil War. The area boomed with rail terminals, barges, lighters, and ferries which crossed the river and New York Bay, carrying coal, food, manufactured goods and passengers throughout the Greater New York area. American Can, Emerson Radio, Lorillard tobaccos, Colgate soaps, and toothpaste, Dixon Ticonderoga pencils - are just a few brand names tat were born here. In the years following World War II, the cities declined, following the collapse of the independent railroad lines and death of the factories. In 1980s the now empty west bank of the Hudson, once crowded with railroad yards, became the place of numerous developments, bringing new residents, new stores and restaurants, and new jobs. Liberty State Park, opened for the Bicentennial in 1976, acquired the abandoned terminal and plant of the Jersey Central and gave the area breathtaking views, ferries to Ellis Island and the Statue of Liberty, and the new Liberty Science Center.

Stereographs are devices capable of building a three-dimensional​ image out of two photographs that have about two and a half inches difference between them so that it could imitate the two eyes’ real field of view. Combining these images into a single one with the help of stereoscope, a person can experience the illusion of the image’s depth. Stereoscope uses the same principle as in human binocular vision. Our eyes are separated by about two inches, so we see everything from two different angles. When the brain combined those views in a single picture, we get the spatial depth and dimension. Stereographs were extremely popular between 1850 and 1930 all around the world. Millions of stereographs were made during that time. There was a broad range of themes: landscape, travel, historical moments, nature disasters, architecture and many others.
