This arrived in the mail yesterday. It's the largest "rock" in my collection to date. It will be tough to beat this one! It came my way involving a trade with two good friends, Bob Berry & Dave LeForge. Bob informed me that he obtained it many years ago through Kevin Lawless and it originally came out of the Don Otis collection.
Don't click on "View Original", unless you are prepared to be smacked in the face with a big rock! :-)
