In 2006, the world of aerial photography entered a new era when the Federal Aviation Commission issued its first commercial drone permit. Within a few short years, recreational drones, with high-resolution cameras attached, were crisscrossing the skies. By 2015 it was estimated that a million had been sold, and aerial photography was suddenly within the budget of millions more.The United States first issued postcards in 1873, at a time when the Federal government was the only entity allowed to print them. That changed in 1898 when postal regulations allowed private companies to mass produce them. Between then and 1907, postal requirements changed three times, which has helped collectors date their cards. From 1898 to 1901, all postcards in the U.S. required %u201cPrivate Mailing Card%u201d to be printed on the back side, where nothing else was allowed except a stamp and the mailing address. The front could have a picture or photograph.In 1901, the shorter %u201cPost Card%u201d replaced %u201cPrivate Mailing Card,%u201d but the reverse could still have only the stamp and mailing address. Again, the front was reserved for a picture or photograph. All these early postcards were known for their %u201cundivided backs.%u201d If a sender wanted to include a message, it had to be on the front%u2014often crammed into the margins. That changed in 1907, when %u201cdivided back%u201d cards were permitted. On these, the right half of the back was reserved for the stamp and address, while the left side could have a written message. Another way collectors date postcards is by surface finish. In general, cards from 1901-1945 had a smooth finish. They often contained images based on black-and-white photographs, some of which were colored by hand. In about 1931, linen-finish cards were introduced. They were made of textured card stock reminiscent of linen fabric. Again, they were often created from black-and-white images, but were now vividly colored by machine, and produced by new printing technologies, which made them less costly. Linen-finish cards remained popular until about 1945, although some were produced as late as the 1960s.
