Gallery of George Rothrock Stereographs of Arizona ca The NYU-X lablocated in the new College of Nursing building at First Avenue, is a catalyst to engage faculty, staff and students to explore emerging technologies, and how the interaction of humans and technology can support teaching, lifelong learning, and innovative health care. To prototype the transition from projection to functional AR, MR and VR simulations, our interdisciplinary team will develop an instrument and educational environment that facilitates enticing research and creates an experiential supercomputing infrastructure that empowers students, faculty, and researchers to develop new knowledge and disseminate powerful new integrated, multimodal tools and techniques.
A real photo postcard RPPC is a continuous-tone photographic image printed on postcard stock. The term recognizes a distinction between the real photo process and the lithographic or offset printing processes employed in the manufacture of most postcard images. In Kodak introduced the No.
Real photo postcards are photographs which have been developed and printed on postcard stock. A caption was often written on the negative which was often glass. Real photo postcards have been produced since the early 's.
But what is it about rp cards that make them command such relatively high prices? There were two main types of postcard printed in the Golden Age. Printed cards were manufactured on a very large scale using printing presses and engraving plates and using one of two main techniques.

Pioneer Era Although the world's first picture postcards date from the s to the mids, most of the earliest American picture postcards extant today are those that were sold at the World Columbian Exposition in Chicago, Illinois, starting on May 1, These were illustrations on government-printed postal cards and on privately printed souvenir cards.
This is the final instalment in my series showing you how to date your old family photographs using physical clues to determine which photographic technique was most likely used. But not all postcards were taken by professionals. Amateur photographers could buy sensitised cards on which to print their own postcards, and inKodak introduced a popular folding camera designed to take postcard-sized prints.
Real Photo postcards are photographs that are reproduced by actually developing them onto photographic paper the size and weight of postcards, with a postcard back. The best way to tell the difference is to look at the postcard with a magnifying glass. If the photo is printed, you will see that it is made up of a lot of little dots, the same as a photo printed in a newspaper.
This guide is meant to aid the collector in identifying and dating real photo postcards, and to act as a reminder that it is impossible to do so with great accuracy. A lthough real photo postcards were made in a variety of ways, they hold one identifiable feature in common. The tonalities of photos are completely continuous to the eye producing true greys, for they are created by the reaction of individual photosensitive molecules to light rather than the transfer of ink from a plate.
Most Real Photo Postcards, abbreviated RPPC, have information on their backs to help in identifying the manufacturer of the photographic paper that was used by the postcard publisher. If you can identify the paper manufacturer, you can approximate the age of the old postcard. If the postcard has a stamp box, click on one of stamp box links below.
The study and collecting of postcards is called "deltiology. The value of old postcards is dependent on a number of factors, including their condition, rarity, age, and subject matter. Similar to other types of vintage and antique collectibles, postcard values are based on a specific set of criteria that affect the value of antique and vintage postcards.
