A New York Times bestseller! "A wonderful and astonishing thing, the kind of book that makes child laugh and adult chuckle, and both smile in appreciation. . . . Charmingly wicked." -- The New York Times A bear's hat is gone, and he wants it back. Patiently and politely, he asks the animals he comes across whether they have seen it. None of them have. Have you seen it? Jon Klassen's beloved tale plays out in sly illustrations brimming with visual humor -- and winks at us with a wry irreverence that will leave readers of all ages thrilled. Available at last in a board book format, this #1 New York Times bestseller is a true modern classic.
