By 1853, an estimated three million daguerreotypes per year were being produced in the United States alone. One of these original Morse Daguerreotype cameras is currently on display at the National Museum of American History, a branch of the Smithsonian Institution, in Washington, D.C. A flourishing market in portraiture sprang up, predominantly the work of itinerant practitioners who traveled from town to town. For the first time in history, people could obtain an exact likeness of themselves or their loved ones for a modest cost, making portrait photographs extremely popular with those of modest means. Celebrities and everyday people sought portraits and workers would save an entire day's income to have a daguerreotype taken of them, including occupational portraits.
