The U.S. Postal Service has continued its tradition of honoring the Stars and Stripes by issuing Four Flags Forever stamps.

This quartet of stamps features a 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 Four Flags stamps are available in booklets of 20 and coils of 100. They are being sold for 45 cents each, $9 per booklet and $45 per coil. They can be bought at Post Offices nationwide, online at usps.com and by phone at 800-782-6724.

To schedule a presentation for your community, club or group on how the Postal Service brings the Post Office to your home or office computer, call 239-573-9638.

Mr. Zip’s Tip: “Save Vanishing Species” is the Postal Service’s fourth semi-postal stamp. Semi-postal stamps are sold above the cost of first class postage to raise funds. Proceeds from the Save Vanishing Species stamp goes to the Multinational Species Conservation Fund. Previous semi-postal stamps have raised funds for:

– Breast Cancer Research

– Assistance to the families of emergency relief personnel killed or permanently disabled in connection with the terrorist attacks of September 11, 2001 and

– Assistance to the programs and organizations fighting domestic violence.
