Here's an interesting casino item that should appeal not only to token collectors, but to fans of the Frontier Hotel, or of Dean Martin. A first-issue
1967 token is enclosed in a cover with transparent window and postmarked at the Las Vegas post office on opening day of the Frontier. Above the token is Dean's autograph. The inset at the bottom is a view of the back of the envelope showing the postmark and cancel.
