There are 5 of these pink matchcover varieties (that I know of) from the New Frontier in Las Vegas. This was the hardest for me to find. Front says "Hotel", with no mention of casino. Inside does not mention a casino, and does have the Los Angeles telephone with the "Bradshaw" exchange rather than "Dudley".

Not my auction, but if you collect older Las Vegas front striker matches, you may need this one! Condition is not perfect, but price is pretty low.
