While neither of us is into stamp collecting (Doug gave up the hobby decades ago), we and the Smithsonian National Postal Museum were both right in the area, so we went in for a meander.
The museum has lots of exhibits and a variety of historical items on display, including a current exhibit on baseball that had nothing to do with postage stamps (but perhaps everything to do with a postmaster with an interest in the game).
Mail crime, stamp fraud, major disasters, and printing mistakes are all covered. Who knew the postage museum would be so full of drama!
America’s postal history is presented, from how it got started to how it gets delivered. The museum has nearly six million items in its collection, only a fraction of which is thankfully on display.
