Beloved children’s book author Margaret Wise Brown died in 1952, but she has a new work coming out in May.

Little Golden Books will publish “Margaret Wise Brown’s Manners,” a book that uses cute critters to demonstrate good manners.

“There is a way to talk when others are talking,” reads one page by the author of “Goodnight Moon,” “and a way to listen when others are talking.”

In 1990, biographer Amy Gary, who wrote “In the Great Green Room: The Brilliant and Bold Life of Margaret Wise Brown,” discovered a trunk full of unpublished manuscripts in Brown’s sister’s barn.

“Margaret was able to see the world through the lens of a child in a poetic, sly way,” said Diane Muldrow, Golden Books’ editorial director.
