Considered to be the first modern picture book, the story of the old man who sets out to find a cat for his wife

Author/Illustrator: Wanda Gag
Published: Penguin Books, 1928

Considered to be the first modern picture book, the story of the old man who sets out to find a cat for his wife and instead brings home "hundreds of cats, thousands of cats, millions and billions and trillions of cats" is simple yet enchanting. When the vain cats eat each other up in a fight over which one is the prettiest, a scrawny kitten becomes the old couple's pet. Winner of the Newbery Medal (before the Caldecott Award was even established), Millions of Cats is the oldest picture book still in print.
