INDIANAPOLIS, IN — The U.S. Postal Service continues its tradition of honoring the Stars and Stripes with the issuance of Four Flags 45-cent First-Class Forever stamps on June 1 at the National Philatelic Exhibitions stamp show.

The quartet of stamps features a bright U.S. flag against a white background. A single word appears on each of the four stamps in large letters:  Freedom, Liberty, Equality and Justice. The black typeface recalls the look of Colonial-era printing.

The stamps are being issued in self-adhesive booklets of 10 stamps for $4.50. Available nationwide June 1, all 200 million stamps can be purchased online at usps.com/shop , by calling 1-800-STAMP-24 (1-800-782-6724) or by visiting post offices.

“The Four Flags Forever stamps were originally issued on February 22 in booklets of 20 and coils of 100 and quickly became some of our best-selling stamps,” said U.S. Postal Service Stamp Services Manager Stephen Kearney, referring more than 800 million sold to-date of 3.7 billion printed. “We created this new format as a customer convenience for those who want to carry 10 stamps in their wallet or purse.

The beauty of Forever stamps is that they are always good for mailing a one-ounce First-Class letter anytime in the future, regardless of price changes.

The flag illustration by the late Arnold Holeywell is based on a photograph taken by art director Howard Paine of Delaplane, VA, who also served as the typographer for the stamp.
