From The Indianapolis Star, Tuesday, October 11, 1921: The word “Go” flashed by a mammoth electric sign atop the Merchants National Bank Building and the blowing of factory whistles across Indianapolis announced the opening of the great Industrial Exposition yesterday evening at the Manufacturers’ Building on the fairgrounds. More than 11,000 visitors passed through the main entrance to see, under one roof, 383 exhibits displaying Indianapolis made products. During the week-long event, the public will get a better idea of the diversity in the city’s vast industrial resources that insures steady work for Indianapolis men and women. Seven hundred and eighty articles are manufactured in the city from tacks to automobiles and automobile accessories, from the printing of books to the making of tractors, from turning out phonographs to building milling machinery, and from manufacturing popcorn machines to men’s clothing.
