Piton Signed by Royal Robbins & Layton Kor and Bird Beak Made & Signed by Jim Bridwell

About Robbins: Royal Robbins (February 3, 1935 - March 14, 2017) was one of the pioneers of American rock climbing. After learning to climb at Tahquitz Rock, he went on to make first ascents of many big wall routes in Yosemite. As an early proponent of boltless, pitonless clean climbing, he, along with Yvon Chouinard, was instrumental in changing the climbing culture of the late 1960s and early 1970s by encouraging the use and preservation of the natural features of the rock. He went on to become a well-known kayaker.

About Kor: Layton Kor (June 11, 1938 - April 21, 2013) was an American rock climber active in the 1960s, whose first ascents and drive for climbing are well known in the climbing world. His routes included many climbs in Eldorado Canyon, near Boulder, Colorado, The Diamond on Longs Peak, towers in the desert southwest, and Yosemite National Park, among other locations. Notable among his first ascents is the Kor-Ingalls Route on Castleton Tower and The Finger of Fate Route up the Fisher Towers' Titan; both routes are recognized in the historic climbing text Fifty Classic Climbs of North America. Kor also authored the book Beyond the Vertical. Kor received the 2009 American Alpine Club's Robert & Miriam Underhill Award for outstanding climbing achievement.

About Bridwell: Jim Bridwell (July 29, 1944 - February 16, 2018) was an American rock climber and mountaineer, active since 1965, especially in Yosemite Valley, but also in Patagonia and Alaska.

He was an apprentice to Royal Robbins and Warren Harding (climber). He was the unofficial leader of the Stonemasters. Bridwell is credited with over 100 First Ascents in Yosemite Valley, in addition to conducting the first one-day ascent of The Nose of El Capitan on May 26, 1975 with John Long and Billy Westbay. He founded Yosemite National Park's Search and Rescue Team (YOSAR), and spearheaded many rescues that became textbook for search-and-rescue operations. He was a leading force in the changing techniques of climbing and an innovator/inventor of widely used and copied climbing gear, including copperheads and bird beaks. Jim resided in Palm Desert, California, USA, until his death on February 16, 2018.
