William H. Martin was a photographer and successful post card manufacturer in the early 1900s. In 1894, Martin took over a studio in Ottawa, Kansas. He used photocomposited trick photography and in 1908, produced wildly exaggerated post cards for commercial trade. His range of cards were so popular that he went into the post card business exclusively.
Within a few years, his trick photos made him wealthy. He sold the business in 1912, and founded the National Sign Company.
