The most famous of all United States Railroad stations is celebrating 100 years of service today.

Grand Central Terminal (GCT) in New York City has been serving travelers for a century now.  

Originally owned by the New York Central Railroad, trains such as the 20th Century Limited departed daily from its underground tracks.

The US Post Office did a special Express Mail Stamp to commemorate the occasion. 

A beloved New York City landmark turns one hundred years old in 2013, and the U.S. Postal Service is celebrating with the Grand Central Terminal Express Mail stamp. The train station officially opened on February 2, 1913, and was soon recognized as one of the most majestic public spaces in the world.

The stamp art captures the grandeur of this architectural masterpiece with an illustration of the main concourse. Early morning sunlight streams through the 60-foot-tall windows, illuminating the people below. In the foreground, travelers gather near the round information booth topped with its famous four-sided clock. The concourse's sky ceiling stretches overhead, decorated with a mural of constellations and figures of the Zodiac.

The graphic illustration was created by artist Dan Cosgrove, working with art director Phil Jordan. 

The Grand Central Terminal Express Mail stamp is being issued in self-adhesive sheets of 10 at the $19.95 rate, or $199.50 per sheet.

So Happy 100th Birthday Grand Central Terminal and here's to another century of servicea
