Le photographe
Ansel Easton Adams est un photographe et écologiste américain, connu pour ses photographies en noir et blanc de l'Ouest américain, notamment dans la Sierra Nevada, et plus particulièrement du parc national de Yosemite. Une de ses plus célèbres photographies s'intitule Moonrise, Hernandez, Nouveau-Mexique. En collaboration avec Fred Archer, Adams développa le zone system, procédé qui permet de déterminer l'exposition correcte ainsi que l'ajustement du contraste sur le tirage final. La profondeur et la clarté qui en résultent sont la marque de fabrique des photographies d'Ansel Adams et de ceux à qui il a enseigné la technique. Dans un premier temps, Adams utilisera des appareils photographiques grand format (plus que 4 × 5 pouces), qui malgré leur taille, leur poids, le temps de mise en place et le prix des films sont un bon moyen, de par leur résolution élevée, de s'assurer du piqué de l'image. Adams fonda le Groupe f/64 avec ses amis photographes Edward Weston et Imogen Cunningham, qui à leur tour, mettront en place le département de la photographie au sein du Museum of Modern Art. Les photographies intemporelles et visuellement saisissantes d'Ansel Adams sont de nos jours encore reproduites sur une grande variété de supports : calendriers, posters, livres, faisant de ses clichés des images célèbres et reconnaissables. Une réserve de nature sauvage porte désormais son nom, au sud du parc national de Yosemite, en Californie. 

Le relief 
Le Grand Canyon ou Grand Cañon est un canyon des États-Unis situé dans le Nord-Ouest de l'Arizona. La gorge a été creusée par le fleuve Colorado dans le plateau du même nom et l'empilement de couches géologiques de Grand Staircase. Fondé en 1919, le parc national du Grand Canyon couvre un territoire protégé de 4 927 km2[. Il est fréquenté chaque année par plus de quatre millions et demi de visiteurs. La diversité et la singularité naturelle et paysagère du site l'ont fait reconnaître patrimoine mondial de l’Humanité par l’UNESCO en 1979.

The canyon 

The Grand Canyon (1,857m -  6,093ft deep) also called in Hopi Ongtupqa, in Yavapai Wi:kaʼi:la, in Navajo Tsékooh Hatsoh and in Spanish  Gran Caсуn is a steep-sided canyon carved by the Colorado River in the U.S. state of Arizona in North America. It is contained within and managed by Grand Canyon National Park, the Kaibab National Forest, Grand Canyon-Parashant National Monument, the Hualapai Tribal Nation, the Havasupai people and the Navajo Nation. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.

The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.

For thousands of years, the area has been continuously inhabited by Native Americans, who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon a holy site, and made pilgrimages to it. 

The first European known to have viewed the Grand Canyon was Garcia Lopez de Cбrdenas from Spain, who arrived in 1540. 

The Grand Canyon area has some of the cleanest air in the United States. However at times the air quality can be considerably affected by events such as forest fires and dust storms in the Southwest.

There are approximately 1,737 known species of vascular plants, 167 species of fungi, 64 species of moss and 195 species of lichen found in Grand Canyon National Park. 90 mammal species are found along the Colorado River corridor, of which 18 are rodents and 22 are bats.   

Vintage postcards

Postcards became popular at the turn of the 20th century, especially for sending short messages to friends and relatives. They were collected right from the start, and are still sought after today by collectors of pop culture, photography, advertising, wartime memorabilia, local history, and many other categories.
Postcards were an international craze, published all over the world. The Detroit Publishing Co. and Teich & Co. were two of the major publishers in the U.S, and sometimes individuals printed their own postcards as well. Yvon were the most famous in France. Many individual or anonymous publishers did exist around the world and especially in Africa and  Asia (Japan, Thailand, Nepal, China, Java) between 1920 and 1955. These photographer were mostly local notables, soldiers, official guides belonging to the colonial armies (british french, belgium...) who sometimes had rather sophisticated equipment and readily produced colored photograms or explorers, navigators, climbers (Vittorio Sella and the Archiduke of Abruzzi future king of Italy remains the most famous of them).
There are many types of collectible vintage postcards.
Hold-to-light postcards were made with tissue paper surrounded by two pieces of regular paper, so light would shine through. Fold-out postcards, popular in the 1950s, had multiple postcards attached in a long strip. Real photograph postcards (RPPCs) are photographs with a postcard backing.
Novelty postcards were made using wood, aluminum, copper, and cork. Silk postcards–often embroidered over a printed image–were wrapped around cardboard and sent in see-through glassine paper envelopes; they were especially popular during World War I.
In the 1930s and 1940s, postcards were printed on brightly colored paper designed to look like linen.
Most vintage postcard collectors focus on themes, like Christmas, Halloween, portraits of movie stars, European royalty and U.S. presidents, wartime imagery, and photos of natural disasters or natural wonders. Not to mention cards featuring colorful pictures by famous artists like Alphonse Mucha, Harrison Fisher, Ellen Clapsaddle, and Frances Brundage.
For vintage postcards, subject matter, condition, and rarity, plus general desirability and demand, determine value.
