There's something wrong with this Maya Angelou stamp

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sing because it has an answer; it sings because it has a song" was by her, with one small change: the pronoun "he" has been replaced by "it" on the stamp.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.

A spokesperson for the Postal Service told the Washington Post: "Had we known about this issue beforehand, we would have used one of [Angelou’s] many other works."
