The Shelbourne Hotel might be interested in taking a look at page 672 of the 1998 Las Vegas yellow pages.

Photographs of the hotel's familiar frontage, its lobby and reception desk, are used to illustrate the page, which announces a "special" for first time callers to a Las Vegas telephone number.

What sort of special the advertisers have in mind is not explained, but the page is pitched towards customers adults only interested in "lovely girls" and "exotic females". So the general class of service being offered is evident enough even to the Margin.
