I is for Inverts


Production errors in which one part of a stamp's design is printed upside-down.

printing, but occasionally they slip out and become very sought after.

Some invert errors are produced intentionally by postal administrations.

The most dramatic U.S. accidental inverts have resulted in an upside-down ship, train, and airplane.
