Las Vegas ? The Stardust, the neon-wrapped casino with a mobbed-up past whose 1,065 rooms once set the standard for size on the Las Vegas Strip, witnessed its last roll of the dice Wednesday.

Wistful longtime employees and loyal gamblers gathered for a last farewell to the iconic 48-year-old institution, which is to be razed early next year to make way for Boyd Gaming Corp.’s planned $4 billion Echelon Place resort.

The Stardust opened July 2, 1958, as the world’s largest hotel and catered to middle America with $6-a-night rooms and low-minimum stakes gambling.

But as bigger, classier casinos sprang up around it in the late 1980s and ’90s and patrons began shelling out more for rooms, food and drinks, its luster began to fade.

The resort was noted for its mob connections. In the 1995 movie “Casino,” Robert De Niro played a character inspired by the finely tailored Frank “Lefty” Rosenthal, who ran the hotel-casino in the mid-1970s.
