Photographer Chris Rainier has spent the last two decades documenting tattoo culture. His journeys have taken him through jungles, cities, deserts, and into the territory of New Guinea hill tribes and L.A. street gangs. What he's found is that tattoos are engrained in the consciousness of humans as a way of expressing identity. Join him as he visits the Indonesian island of the Mentawai people, where the ancient ritual of tattooing is rapidly disappearing. Rainier hurries to document this culture before its traditional ways change forever.
