Employees Exercising Horses, H. J. Heinz Company, Pittsburgh, Pennsylvania, circa 1905

Before the 1920s, the H.J. Heinz Company transported their goods by rail and by horse-drawn wagons. The main factory in Pittsburgh, Pennsylvania, had top-of-the-line stables, sometimes referred to as "equine palaces," where the horses received only the best feed and care. In this photograph, employees are exercising the horses on the grounds within the factory complex.
