This is the US postal service's stamp paying tribute to the late, legendary writer Maya Angelou.
Just one problem: while Angelou wrote the memoir I Know Why the Caged Bird Sings, she did not write the quotation on the stamp.
The Washington Post reports the quote is actually from a 1967 book by children's author Joan Walsh Anglund. Anglund, now 89, told the newspaper "a bird doesn't sing because it has an answer; it sings because it has a song" was by her, with one small change: the pronoun "he" has been replaced by "it" on the stamp.
The quote has been widely attributed to Angelou - including by Barack Obama at the National Medal of Arts and National Humanities ceremony last year.
