Here’s the statement off the Eagles homepage:

“We join with many others in mourning the passing of our friend and collaborator, Gary Burden. Gary designed the covers of our first four albums. He was a unique and talented man, a big-hearted adventurous spirit, a Marine, a fluent Spanish speaker, a masterly raconteur, and a true artist. He made an exceptional and lasting contribution to the art of the vinyl LP album cover and he will be missed. RIP, old friend.”
