The Tru-Vue Company of Rock Island, IL debuted their product at the 1933 Century of Progess World's Fair in Chicago, 6 years and a World's Fair earlier than the View-Master® debut. Although the 3D Stereo Filmstrip format was not brand new, (see Novelview, here at the 3Dstereo eMarket) their marketing and choice of titles made them a smashing success, bringing sepiatone 3D Stereo Filmstrips into the homes across America. The original views were initially made with a 5"x7" Stereo Graflex camera and mounted as black and white prints, then copied onto 35mm transparency film. Each filmstrip usually contains 14 stereo pairs. Some 17 years later, after competing for 11 years against the color 3D Stereo reels of View-Master®,
Tru-Vue tried their hand at color too, but was soon purchased by their competitor, View-Master, who needed the lucrative Disney licenses that Tru-Vue had obtained. For about a year, View-Master produced in Portland, Tru-Vue Filmstrips in both color and black & white film (mostly Disney subjects) and then discontinued the product after an 18 year run.
Tru-Vue 3D stereo cards and 2D cards were not made by the Tru-Vue Company, but were a View-Master bargain-priced product, utilizing the Tru-Vue name which they owned after purchasing Tru-Vue.Today, Tru-Vue 3D Stereo Filmstrips, are collected and viewed by a smaller, but extremely active group of collectors, who regard Tru-Vue's coverage of World's Fairs, Hollywood, Night Clubs, Fashion and Risque as unparalleled in the area of 3D Stereo.
About Death Valley National Park:
Death Valley is a desert valley located in Eastern California, in the northern Mojave Desert bordering the Great Basin Desert. It is one of the hottest places in the world at the height of summertime along with deserts in the Middle East.
Death Valley is home to the Timbisha tribe of Native Americans, formerly known as the Panamint Shoshone, who have inhabited the valley for at least the past millennium. The Timbisha name for the valley, tümpisa, means "rock paint" and refers to the red ochre paint that can be made from a type of clay found in the valley.
Some families still live in the valley at Furnace Creek. Another village was in Grapevine Canyon near the present site of Scotty's Castle. It was called in the Timbisha language maahunu, whose meaning is uncertain, although it is known that hunu means "canyon".
The valley received its English name in 1849 during the California Gold Rush. It was called Death Valley by prospectors and others who sought to cross the valley on their way to the gold fields, after 13 pioneers perished from one early expedition of wagon trains. During the 1850s, gold and silver were extracted in the valley. In the 1880s, borax was discovered and extracted by mule-drawn wagons.
On the afternoon of July 10, 1913, the United States Weather Bureau recorded a high temperature of 134 °F (56.7 °C) at Greenland Ranch (now Furnace Creek) in Death Valley.[6] This temperature stands as the highest ambient air temperature ever recorded at the surface of the Earth. (A report of a temperature of 58 °C (136.4 °F) recorded in Libya in 1922 was later determined to be inaccurate.)
Death Valley National Monument was proclaimed on February 11, 1933, by President Herbert Hoover, placing the area under federal protection. In 1994, the monument was redesignated as Death Valley National Park, as well as being substantially expanded to include Saline and Eureka Valleys.
Death Valley's Badwater Basin is the point of the lowest elevation in North America, at 282 feet (86 m) below sea level. This point is 84.6 miles (136.2 km) east-southeast of Mount Whitney, the highest point in the contiguous United States with an elevation of 14,505 feet (4,421 m).[4] Death Valley's Furnace Creek holds the record for the highest reliably recorded air temperature on Earth at 134 °F (56.7 °C) on July 10, 1913, as well as the highest recorded natural ground surface temperature on Earth at 201 °F (93.9 °C) on July 15, 1972.
Located near the border of California and Nevada, in the Great Basin, east of the Sierra Nevada mountains, Death Valley constitutes much of Death Valley National Park and is the principal feature of the Mojave and Colorado Deserts Biosphere Reserve. It is located mostly in Inyo County, California. It runs from north to south between the Amargosa Range on the east and the Panamint Range on the west; the Grapevine Mountains and the Owlshead Mountains form its northern and southern boundaries, respectively.
It has an area of about 3,000 sq mi (7,800 km2). The highest point in Death Valley itself is Telescope Peak in the Panamint Range, which has an elevation of 11,043 feet (3,366 m).
