Not only did they alter the specifics of this process to give their own postcards and prints a unique look, they did much experimentation causing their postcard production to undergo a number of technical changes during the company’s history, which continually altered the appearance of their cards. <i>Phostints</i> are based on creating a continuous toned lithographic image through directly exposing a negative through contact printing to a stone photosensitized with a coating of Syrian asphaltum. By their careful control of the asphaltum in relation to its processing etch they were able to manipulate images in countless ways. It is even possible that they may have combined this technique with elements of the Vidal process. While typically six to sixteen litho-stones were employed to print all the different colors needed to create a single <i>Phostint</i> image, many more optical color variations were possible through their careful alterations of each stone. The precise details of their methods were kept such close trade secrets that when Detroit Publishing went out of business the techniques they developed died with them.</p><p><a href="http://www.metropostcard.com/glossaryp.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.metropostcard.com/glossaryp.html" rel="nofollow">http://www.metropostcard.com/glossaryp.html</a></p><p><br /></p><p>It’s convincingly photographic, but when you look at the details, it looks posterized.</p><p><br /></p><p>[ATTACH=full]155325[/ATTACH] </p><p><br /></p><p>[ATTACH=full]155326[/ATTACH] </p><p><br /></p><p>Anyhow… it shows the railroad tunnel at the Raton Pass on the Santa Fe line.&nbsp; (See?&nbsp; Santa’s right there in the name!)</p><p><br /></p><p>This tunnel was completed in 1879, but reference to the “recently completed” second, lower tunnel, which was finished in 1908, dates this c1910.</p><p><br /></p><p>It’s also cool that it’s a Fred Harvey postcard, likely from one of his souvenir shops, maybe even purchased aboard a train on that same line.</p><p><br /></p><p>[ATTACH=full]155328[/ATTACH][/QUOTE]</p><p><br /></p>
