Passage: Before 1953, Walt Disney's productions were distributed by Winkler Pictures, Powers Pictures, Universal Pictures (Oswald the Lucky Rabbit shorts), Columbia Pictures (1930–1932), United Artists (1932–1937) and RKO Radio Pictures (1937–1953). However, a dispute over the distribution of Disney's first full-length movie, The Living Desert, in the True-Life Adventures series of live-action documentary featurettes in 1953 led to Walt and his older brother Roy O. Disney to form its wholly owned subsidiary, the Buena Vista Film Distribution Company, Inc. (BVDC), to handle North American distribution of their own products. RKO refused to distribute the film. The name "Buena Vista" came from the street in Burbank, California, where the Disney Studios was located (and remains to this day). Buena Vista's first release was the Academy Award–winning live-action feature The Living Desert on November 10, 1953, along with Toot, Whistle, Plunk and Boom, Buena Vista's first animated release. Notable subsequent releases include the foreign film, Princess Yang Kwei-Fei (Most Noble Lady), released in US theaters in September 1956, The Missouri Traveler in March 1958, and The Big Fisherman in July 1959 (the first third-party production financed by Disney).

Passage: The Franco-German art dealer and publisher Siegfried Bing played a key role in publicizing the style. In 1891, he founded a magazine devoted to the art of Japan, which helped publicize Japonism in Europe. In 1892, he organized an exhibit of seven artists, among them Pierre Bonnard, Félix Vallotton, Édouard Vuillard, Toulouse-Lautrec and Eugène Grasset, which included both modern painting and decorative work. This exhibition was shown at the Société nationale des beaux-arts in 1895. In the same year, Bing opened a new gallery at 22 rue de Provence in Paris, the Maison de l'Art Nouveau, devoted to new works in both the fine and decorative arts. The interior and furniture of the gallery were designed by the Belgian architect Henry Van de Velde, one of the pioneers of Art Nouveau architecture. The Maison de l'Art Nouveau showed paintings by Georges Seurat, Paul Signac and Toulouse-Lautrec, glass from Louis Comfort Tiffany and Emile Gallé, jewellery by René Lalique, and posters by Aubrey Beardsley. The works shown there were not at all uniform in style. Bing wrote in 1902, "Art Nouveau, at the time of its creation, did not aspire in any way to have the honor of becoming a generic term. It was simply the name of a house opened as a rallying point for all the young and ardent artists impatient to show the modernity of their tendencies."

The pass provide access into three river sheds. An east-west route ran from the east up the Wind River valley and provided a western route by the Gros Ventre or Hoback Rivers to the Valley of the Snake River in Jackson's Hole. To go south, the traveler would follow the Green River. The Union Pass Route was an extension of a North South Route up the Valley of the Yellowstone. Coming up the Valley of the Thoroughfare, west of the Absaroka Mountains and south of Yellowstone Lake, the trail followed the North Fork of the Yellowstone.
