Updated January 21st: From the Postal Bulletin:
On February 2, 2016, in Philadelphia, PA, the U.S. Postal Service® will issue the Richard Allen First-Class Mail® stamp (Forever® priced at 49 cents), in one design, in a pressure-sensitive adhesive (PSA) pane of 20 stamps (Item 473500).

The stamp will go on sale nationwide February 2, 2016.

The 39th stamp in the Black Heritage series commemorates preacher, activist, and civic leader Richard Allen (1760–1831), an inspiring figure whose life and work resonate profoundly in American history. This stamp coincides with the 200th anniversary of Allen’s founding of the African Methodist Episcopal (AME) Church, one of the most important institutions in African-American life, and his election and consecration as its first bishop. The stamp art is a portrait of Allen, a detail from an 1876 print titled “Bishops of the A.M.E. Church” from the collection of the Library Company of Philadelphia. Art director Greg Breeding designed the stamp.
