Turin International
The Turin International was a world's fair held in Turin in 1911 titled Esposizione internazionale dell'industria e del lavoro. It received 7,409,145 visits and covered 247 acres. Summary

The fair opened on 29 April, was held just nine years after an earlier Turin fair which had focused on the decorative arts, and at the same time as another Italian fair in Rome, also with an arts focus. This fair deliberately distinguished itself by focusing on industry and labour. The fair was held in the Parco del Valentino (as were the three previous Turin fairs in 1884, 1885 and 1902 and the subsequent 1924 Turin fair). Participants

Participating countries were Argentina, Austria, Belgium, Bolivia, Brazil, Bulgaria, Chile, China, Colombia, Denmark, Ecuador, France, Germany, Greece, Hungary, Italy, Japan, Mexico, Netherlands, Nicaragua, Peru, Russia, Serbia, Siam, Spain, Switzerland, Turkey, United Kingdom, United States and Uruguay.
