Updated June 10th:
On July 12, 2017, in Chadds Ford, PA, the U.S. Postal Service® will issue the Andrew Wyeth stamps (Forever® priced at 49 cents), in twelve designs, in a pressure-sensitive adhesive (PSA) pane of 12 stamps (Item 475000). The stamps will go on sale nationwide July 12, 2017.

This pane of stamps celebrates the centennial of the birth of Andrew Wyeth (1917–2009), one of the most prominent American artists of the 20th century. Working in a realistic style that defied artistic trends, Wyeth created haunting and enigmatic paintings based largely on people and places in his life, a body of work that continues to resist easy or comfortable interpretation.

This issuance includes 12 stamps that feature a detail of a different Andrew Wyeth painting. The paintings are: “Wind from the Sea” (1947), “Big Room” (1988), “Christina’s World” (1948), “Alvaro and Christina” (1968), “Frostbitten” (1962), “Sailor’s Valentine” (1985), “Soaring” (1942–1950), “North Light” (1984), “Spring Fed” (1967), “The Carry” (2003), “Young Bull” (1960), and “My Studio” (1974). The selvage shows a photograph of Wyeth from the 1930s. Art director Derry Noyes designed the pane.

From the USPS, November 22nd, 2016:

Mastering a realistic style that defied artistic trends, Andrew Wyeth (1917-2009) created haunting and enigmatic paintings based largely on people and places in his life — a body of work that continues to resist easy or comfortable interpretation. Finding endless inspiration both in his hometown of Chadds Ford, PA, and in rural Maine, he scrutinized the lives, houses and personal belongings of people around him, sometimes painting their portraits but just as often using objects and places to represent them. 2017 is the centennial of Wyeth’s birth. With subtle symbolism and eerie implications, his work invites us to reinterpret his personal vision. Derry Noyes art directed and designed this pane of 12 stamps.
