This is a set of the popular board book "Goodnight Moon" and the bonus book "Do Not Bring Your Dragon to the Library." Both are popular stories for which Japanese editions have been published. "Goodnight Moon" is a thick board book, easy for small children to handle. It was purchased for around 3000 yen. There is a tear at the top of the spine, as shown in the image. "Do Not Bring Your Dragon to the Library" is also a popular picture book with a Japanese edition. It is a larger size. I received it at a school in LA. It has a price tag of $14. There is a tear on the last page, which is why it is included as a bonus. I am offering this at a low price, so please consider purchasing them together.
