一只熊的帽子不见了，他想找回来。他耐心而礼貌地询问他遇到的动物是否见过它。他们都没见过。你见过它吗？这本《纽约时报》****的畅销书终于出了纸板书，是一部真正的现代经典。

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.
