When he puts on his sailor suit, sailor hat, and sailor whistle, the boy in this book is ready for a journey. He imagines himself on a ship, sailing across the sea, in search of treasure. A sailor's life is dangerous. But a sailor must be brave no matter what happens.

In this charming story about imagination and adventure, told with Uri Shulevitz's signature playfulness and style, a little boy learns how to be courageous, both on the high seas and at home. The tale is based on a childhood memory from the time when the author/illustrator and his family lived in Warsaw on the eve of World War II.
