Message Monsters 2021

Add color, creativity, and humor to your mail with the interactive Message Monsters Forever stamps. The pane of 20 contains four playful creature designs: a round rosy monster with a sunny belly, a striped four-armed character, a yellow squid-like creature with many eyes, and a red rascal wearing shorts. Dozens of self-adhesive accessories—including hats, crowns, hearts, stars, flowers, speech balloons, and thought bubbles—allow senders to personalize the monsters and their messages. Antonio Alcalá designed the pane with original artwork by children’s author and illustrator Elise Gravel. Issued in 2021, these Forever stamps are always equal in value to the current First-Class Mail one-ounce rate.
