William H. "Dad" Martin

William H. Martin was a photographer and successful real photograph post card (RPPC) manufacturer starting in September 1908. In 1894, Martin took over a studio in Ottawa, Kansas. He used photocomposited trick photography and, in 1908, produced wildly exaggerated postcards for commercial trade. His range of cards were so popular that he went into the postcard business exclusively.

Within a few years, his trick photos made him wealthy. He sold the business in 1912, and founded the National Sign Company.
