Mystery Message Forever Stamps, 2021 Sheet – Greeting Cards and Letters

The seemingly random patterns were carefully placed so that when put all together, the message reads (here is a “spoiler alert”): “More Than Meets the Eye!” The reverse side of the pane also provides the solution.

Art director Antonio Alcalá designed the stamp. The Mystery Message stamp is being issued as a Forever stamp. This Forever stamp will always be equal to the current First-Class Mail 1-ounce price.
