Fun flair

Message Monsters, the Postal Service’s most playful, customizable Forever stamp design ever, will be released Sept. 24.

The pane of 20 stamps features four monster illustrations that can be dressed up with dozens of self-adhesive accessories on the selvage.

The accoutrements include cartoony voice balloons and thought bubbles with exclamations and salutations, hats and crowns, hearts, stars, daisies and other fun flair.

Antonio Alcalá designed the pane with original artwork by Elise Gravel, author and illustrator of popular children’s books.

The stamps will be available at Post Offices and
