"Living in Santa Fe in New Mexico, I"ve always had a fascination with the First Nations peoples," said Rainier. "This photo was taken in Utah. They"re thought to be about 4,000 years old but they"re in exquisite condition. You can imagine an ancient person putting their hand up to the red wall, taking the ochre and applying the paint onto the rock. These handprints have a powerful echo from eons ago. I imagine a group of hunters sitting in the shade, maybe saying "Why don"t we put our signature here?" For me, it could be about existence, saying: "We are here.""
