Although you can't tell from this distance, this poster, created by a company called http://www.litographs.com/ , is made up of the full text of one of Kipling's Just-So Stories. It was offered as a gift to teachers who followed the company on Twitter. It is perfect for a school library as you can see all the amazing creatures are spilling from a book.
I have seen other pictures done this way and it's really fascinating to firs see the picture but then to realize it's made up of words. The students will have fun looking at that.
