Official Announcement On December 1, 2010, in Washington, DC, the Postal Service™ will issue a First-Class Mail® Lady Liberty/Flag Forever se-tenant pair (two designs) in a pressure-sensitive adhesive (PSA) coil of 100 stamps (Item 787900). The stamps, designed by Terrence McCaffrey, USPS®, go on sale nationwide December 1, 2010.

The U.S. Postal Service® will introduce two new First-Class Mail Forever® stamps featuring photographs of world-recognized symbols of the United States: the Statue of Liberty and the American flag. The photograph of Lady Liberty is by Raimund Linke and the U.S. Flag photograph is by Ron Watts.

The stamps will be issued in a coil format and known as Lady Liberty and U.S. Flag. Forever stamps are always equal in value to the current First-Class Mail 1-ounce rate.

Security The microprinted "4ver" is on both stamps.  On the Flag it is printed on the lower edge in the middle of the lowest red stripe.  On the Liberty Head, it is printed at the hairline, just to the right of the left eye, as you look at the stamp.
Note These Sennett Security Products coils come in stamp 'sticks' up to 10 rolls high, and are held together with tiny pieces of uncut paper called bridges.
Note Seam lines, when present on this issue, can be found near the die cut, two die cut rows left of the plate number stamps.  Seam lines can be any of the colors found in the plate number and are caused by ink build up at the edge of the offset printing mat.
