After graduating, Boyd returned to El Paso and later set up a workshop in Valentine where he created artwork made of polyester resin. However, on May 31, 1973, his studio burnt down including 15 pieces of the artwork that he had planned to exhibit. Having also lost his art supplies in the fire, he started to use the skulls of animals including a cow and a bull that had died in a flood on which to paint, inspired by a painted turkey breastbone sent to him as a present by
Rick Griffin. Elder presented two of his works to the Eagles in Dallas in late 1974, one of which was then chosen for the cover of
One of These Nights. The artist was paid $5,000 for the work. Elder continued to produce a number of skull artwork after the Eagles covers. He also produced works in various media such as plastics and resins, holographic foil and aluminum, as well as multi-media works. He served as caretaker for an art installation called
Prada Marfa, a fake
Prada store erected in Valentine. He produced artwork in Valentine and showed them in the nearby town of
Marfa, Texas. He also worked in California and Hawaii. ==Personal life==
