The United States Post Office is commemorating Shirley Chisholm this year for its annual Black History Month stamp series. Chisholm, the first black congresswoman in the U.S. and the nation’s first African American to run for Democratic presidential nomination, also happened to be a fierce political icon. As such, the Chisholm stamps promise to elevate any kind of mail you’ve got to send.

New Yorkers who are feeling extra festive: head to the Shirley Chisholm post office in Brooklyn to pick up your Chisholm stamps. They’re being released tomorrow.
