The new Mystery Message Forever stamp is designed to put your sleuthing skills to the test! Featuring bright colors and interesting shapes, the stamp design is a visual riddle spelling out a difficult-to-discern message. Each colorful square contains a letter in an interesting pattern.

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.
