I agree with James....I've never seen or heard of the Diamond Jim's name on a Las Vegas ashtray, either. We have one from Diamond Jim's in Jackpot, and I LOVE the logo! I recently started scanning a few of our trays (we have 800-900 including some duplicates), and that happens to be one that I scanned...here's a link to the page:
