A large ornately decorated building, The Mills Edisonia Spectatorium was billed as the only free admission entry on the Pike. The edifice housed several hundred coin-operated machines that showcased movies (mostly about (travel), and many commodities such as candy, gum, peanuts, cigars, and lead stamps.
Other machines gave out the Fairgoers' weight, strength, grip power, lung capacity (for singing), lifting, and hitting power, that is, after the coin was paced into the slot.
The travel machines, provided by Thomas Edison's Company, showcased exotic locales of Europe and the United States. One viewer could see San Francisco from Telegraph Hill, or see the Swiss Alps, or Paris.
The building was conceived by a partnership with Thomas Edison; a energetic, yet poor man- Herbert S. Mills, conceived the idea of perfecting the slot machine. Through his invention, Mills created the Mills Novelty Company with the capital of 500,000 dollars. By the time of the Fair, Mills was famous for his slot/vending machines.
