The first-day ceremony for the United States Shirley Chisholm forever stamp was scheduled for Jan. 31 in Brooklyn, N.Y. The 11 a.m. event was to take place at the Brooklyn Borough Hall, 209 Joralemon Street.

The Chisholm stamp is the 37th issue in the long-running Black Heritage commemorative series.

Chisholm was the first black woman to serve in Congress and was a candidate for the Democratic presidential nomination in 1972.

The stamp design shows a painting by Robert Shetterly of Chisholm against a blue background. The portrait is one of a series of paintings by the artist titled Americans Who Tell the Truth.

The design is shown here with a mock-up of the first-day cancel.

U.S. Postal Service spokesman Roy Betts told Linn’s that the Chisholm stamp design would not be formally unveiled until the Jan. 31 event.
