A Valentine Diner was a prefabricated mail order small diner produced in Wichita, Kansas after the Great Depression.  In 1947, manufacturing was taken over by the Valentine Manufacturing Company. After World War II and the implementation of the Interstate Highway System in the U.S. in the late 1950s, prefabricated diners saw a boom in business as motorists took to the roads in greater numbers for longer journeys and would stop for a meal. Valentine Diners were produced until the 1970s, and several survive as operating business (sometimes as a restaurant, sometimes as other businesses) around the United States today.
