In the spring of 1998 four buddies from North San Diego county were exploring an abondoned silver mine in the Mojave desert. They were hundreds of feet below the ground and ironically they struck GOLD! What they later learned they had found in a deep offshoot tunnel was the oldest original pair of Levi's blue jeans from the very first production run of the "501" line that exist on the earth today!

"This pair has been personally inspected and verified as authentic by world renowned Levi Strauss & Co. historian, Lynn Downey, as well as the President and CEO of Levi Strauss & Co., Robert Haas, at the Levi Strauss Headquarters located at 1155 Battery Street, in San Francisco, California, on July 15, 1998. Lynn actually let out the cinch strap buckle to show me that it was still complely functional and not to worry about hurting it, which she was correct. It's a little rusty, but still works fine. Mr Haas turned the jeans inside-out and remarked at their incredible condition and stitching and wondered why LS & CO. hadn't purchased them, upon which he was told that they had just been discovered a few months before."
