This stamp issuance celebrates the 50th anniversary of the Woodstock Music and Art Fair, held in the small farming community of Bethel, New York, in August 1969. It was the most famous rock fair in history and an expression of the youth counterculture of the 1960s. The stamp art, designed by art director Antonio Alcalá¡, features the image of the dove from graphic artist Arnold Skolnick’s promotional 1969 poster for the fair along with some of the poster’s words: “3 Days of Peace and Music.” In the stamp art the words are stacked in the background in brilliant colors along with the year 1969, USA, and Forever (the value of the stamp). The white dove stands in the foreground.
A 50th anniversary reunion festival is planned for August 15-18, 2019, in Watkins Glen, NY (about 115 miles WNW or 150 miles driving).

Four whimsical se-tenant stamps celebrate the fun of America’s state and county fairs. The stamps were designed to work together as a panorama of fair activities, while each stamp also works as an individual picture. The stamp on the far left shows farmers unloading produce behind a white fence. In the second stamp, a child holding a chicken sits atop the same fence, with carnival rides — a Ferris wheel and merry-go-round — in the background. Those rides can be seen in the third stamp, where some fairgoers admire the livestock behind the fence while others walk, balloons in hand, toward a sweets stand. The last stamp shows children at the stand buying treats from the vendor. The art director was Greg Breeding. Mike Ryan designed the stamps with original art by Mick Wiggins.

Art director William J. Gicker designed the stamps.

With this stamp, the 32nd in the Literary Arts series, the Postal Service honors poet Walt Whitman (1819—1892) on the bicentennial of his birth. The stamp features a portrait of Whitman based on a photograph taken by Frank Pearsall in 1869. In the background, a hermit thrush sitting on the branch of a lilac bush recalls “When Lilacs Last in the Door-yard Bloom’d,” an elegy for President Abraham Lincoln written by Whitman soon after Lincoln’s assassination on April 14, 1865. Considered by many to be the father of modern American poetry, Whitman broke away from dominant European poetic forms and experimented with free verse and colloquial expressions, writing powerfully about nearly every aspect of 19th-century America. The artist for the stamp was Sam Weber. Art director Greg Breeding designed the stamp. The words “THREE OUNCE” on this stamp indicate its usage value. Like a Forever stamp, this stamp will always be valid for the rate printed on it.
On September 12, 2019, in Huntington Station, NY, the United States Postal Service® will issue the Walt Whitman stamp (Non-denominated priced at the 3-ounce rate) in one design, in a pressure-sensitive adhesive pane of 20 stamps (Item 120300).

The Postal Service celebrates USS Missouri (BB-63), America’s last battleship, with the issuance of a commemorative stamp in 2019, coinciding with the 75th anniversary of Missouri’s commissioning on June 11, 1944. The stamp art depicts Missouri in the disruptive camouflage she wore from her commissioning until a refit in early 1945. Missouri earned numerous combat awards and citations during her decades of service, which include World War II, the Korean War and Operation Desert Storm. She played a momentous role when she hosted the ceremony marking Japan’s surrender and the end of World War II. Designed by art director Greg Breeding, the stamp features a digital illustration by Dan Cosgrove.
The famed American battleship is being honored to coincide with the 75th anniversary of her commissioning on June 11, 1944. The battleship was affectionately nicknamed “Mighty Mo,” and had one of the most historic roles during World War II. On Sept. 2, 1945, military officials from the Allied powers and imperial Japan convened on her deck and signed the documents confirming Japan’s surrender and ending the war.
