Daniel, can you share some of your favorite stories about stamps that highlighted American innovation?

Sure.

I think one of the ones that stands out for me is the fact that the U.S. in 1912 issued the first postage stamp anywhere in the world that depicted an airplane.

And that was part of a parcel post series issued in 1912.

Airplanes were... a brand new technology at that time, breakthrough in transportation.

And they were seen as the future of mail transportation.

So also in that series is a mail ship and a mail train.

Why does recognition on something like a stamp tend to lag behind reality?
