I tried my damnedest to find information on Gian Marco Agazzi, the photographer of The Red Men of Indian Wrestling, but to no avail.
The Red Men of Indian Wrestling refers to Kushti; the traditional and ancient form of wrestling that was, and still is, practiced in India, Pakistan and other neighboring countries. The Kushti (also known as Pehlwani) wrestling performed on clay mixed with ghee. Its practitioners face grueling daily training, a strict diet and celibacy.
