A post office since the seventies, the booking hall is a fantastic relic of the "golden age of travel." According to www.nyc-architecture.com/LM/LM006-CUNARDBUILDING.htm the hall is "awash in things marine: starfish, seahorses, shells, sirens, an albatross, and the vessels of Columbus and others. All are celebrated in paintings, murals, and medallions. The grandly presented theme underscores the power and reach of the Cunard Line when its new headquarters opened in 1919."
25 Broadway's new tenants is going to be, according to the New York Times, The National Sports Museum, and will be the permanent home of the Heisman Trophy. Hopefully the murals and decoration in the Booking Hall will still be accessible to the public.
(although I suspect that it will cost $35 to get in, and the interior of the building will be obscured by floor to ceiling video screens and tee-shirt displays. Prove me wrong National Sports Museum)
Update: Curbed.com is reporting that the National Sports Museum is, in fact, finding a home at the former Standard Oil Building at 26 Broadway. (moral: the NYT may be the paper of record, but sometimes they can't count. Or perhaps the Sports Museum changed their minds).
26 Broadway (which is reflected in the windows in the picture above) was originally built in 1886. It was enlarged and expanded in 1896 and again from 1920 - 1926.
Now -- what is going happen at 25 Broadway? A new, improved, Post-office?
