20-Minute Itinerary


Stop #1 (Museum Level 2, William H. Gross Stamp Gallery)

Inverted Jenny

Inverted Jenny

24c Curtiss Jenny invert block of four, 1918

Go into the William H. Gross Stamp Gallery and find the “Gems of American Philately” exhibit. There, you will see four “Inverted Jenny” stamps, still together in what we call a “block of four.” This rarity is treasured by stamp collectors so much that it is the equivalent of the Louvre’s Mona Lisa.  

Take a close look. Just like a work of art, the beauty is in the details. But with a rare stamp, the beauty is also in its flaws. To understand how this mistake happened (plane printed upside down), watch the film in the theater behind you or visit the Spider Press adjacent to the exhibit.

Stop #2 (Museum Level 2, William H. Gross Stamp Gallery)

Amelia Earhart’s Flight Suit

Amelia Earhart’s Flight Suit

This famous female pilot broke flying records in the air, and while on the ground she shared her stamp and cover collection. You can see relics from both parts of her life displayed here, on the touch screen interactive and in the adjacent cases.

The flight suit kept her warm and safe on her adventures. The envelopes with special cancels, carried aboard those flights, instantly created a collectable desired by stamp experts. They pre-paid for the envelopes flown aboard her plane which she would postmark with the dates of the flight.


Stop #3 (Museum Level 2, Historic Lobby)

Historic Lobby

Historic Lobby Ceiling

As you transition from upstairs to downstairs, pause to look up at the ceiling in the Historic Lobby. This building was constructed as a companion to Union Station by the same architect, Daniel H. Burnham. The hexagonal shapes in this ceiling echo the shapes in the Union Station ceiling. Both are of the Beaux-Arts style, promoting balance and symmetry. The building opened in 1914 as the D.C. city post office and served as the central hub for all mail going in and out of the nation’s capital. It was built adjacent to Union Station because all mail leaving or coming into a city like this travelled by train.

Stop by the postcard writing desk to create your own mail piece to send. One of the postcards features the building and how it looked in 1914.


Stop #4 (Museum Level 1, Railway Post Office in the Atrium)

Owney the Dog

Owney the Dog

In the museum’s atrium, you will see a Railway Post Office on your right in the “Moving the Mail” exhibit. In addition to the train car, you can find one of its most loyal patrons: Owney the Dog. The story of Owney, the scruffy mutt who became the unofficial mascot of the Railway Mail Service (RMS) in the late 19th century, is one of the most popular exhibits in the National Postal Museum. Visit Owney to learn how he became the most well-traveled and well-loved postal dog in history.

Why does he have all these metal tags on his harness? Take a look at this video to learn more about his adventures.

Snap a selfie with this adventurous dog and share with your friends and the museum @PostalMuseum.


Stop #5 (Museum Level 1, Behind the Badge exhibit)

Anthrax Letter and Mailbox

Anthrax Letter & Mailbox

In the Behind the Badge exhibit, you will find many stories and objects from crimes postal inspectors have solved to protect those who use the mail. One of their most memorable cases was in 2001 when anthrax was sent through the mail. At the end of the Behind the Badge exhibit, find the blue USPS mailbox covered in white powder. This collection box was the one the anthrax letters were mailed from. The powder is from its decontamination treatment. In the adjacent case, you can press the button to shine light on the envelope and letter that originally contained anthrax.

The first of these letters killed Florida newspaper employee Robert Stevens. Others were found addressed to politicians and reporters. In the end, 22 people were infected with spores from the anthrax letter attacks, including nine U.S. postal workers. Two of these postal workers died, and the Washington D.C. mail sorting facility where they worked now bears their names.


Stop #6 (Museum Level 1, Atrium)

Museum Shop

Museum Shop & Stamp Store

Adjacent to the Behind the Badge exhibit is our Museum Shop and Stamp Store – browse fun postal and stamp-themed goods that we sell in the shop! Now you can take home your very own Inverted Jenny rarity (in t-shirt or mug form).

In addition to receiving special cancellations when dropping off a letter here (please ask for a special cancellation), the museum’s Stamp Store holds a variety of stamps that you can’t find in your local Post Office. Ask the USPS clerk at the Stamp Store for a binder that shows their available inventory.
