Although lithography was invented in 1798, it was at first too slow and expensive for
            
 poster production. Most posters were woodblocks or metal engravings with little color or
            
 design. This all changed with Cheret's three stone lithographic process, a breakthrough
            
 that allowed artists to achieve every color in the spectrum with as little as three stones -
            
 red, yellow, and blueprinted in careful registration. 
            
  Although the process was difficult, the result was a remarkable intensity of color
            
 and texture, with sublime transparencies and nuances impossible in other media (even to
            
 this day). This ability to combine words and images in such an attractive and economical
            
 format finally made the lithographic poster a powerful innovation. Starting in the 1870s

 during this period. These were changing times. The middle class started to have access to consumer
            
 goods. This new consumer-oriented economy created a need for a medium to reach the
            
 masses of people with product information. The poster filled this need. To reach the
            
 people they had to be loud, colorful, easy to read, and easy to understand. More
            
 importantly, they had to be inexpensive as they only lasted for such a short period of time.
            
  Jules Cheret pioneered color lithography as an economical means of advertising.
            
 His innovations with color and shading produced images that convey their message in a
            
 matter of seconds while still proving interesting more than one hundred years later with
            
 complex and subtle color harmon...
