Here is a beautiful picture book about Mary Poppins. It is a 'Disney Storybook Favorite' - a modern re-print of what was originally a Little Golden Book in 1964, illustrated by Beverly Edwards and Leon Jason. This picture book - 'Mary Poppins - A Jolly Holiday' - is an adaptation from the movie, not from the chapter book by P.L Travers. Right now I am reading the first of the Mary Poppins chapter books to my 6-year-old and remembering the days when I lived inside these books for a time as a child.

When I was Googling for images of the P.L. Travers books, I came across an article about some of the differences between the movie and the book. I was saddened to read a few comments about how some people hadn't even known it was a book, they had only known about the movie!
I was VERY EXCITED to read on Wikipedia that a movie called "Saving Mr. Banks" is in the works!! It's a movie about the production of the movie Mary Poppins! (How meta is that - a movie about a movie??) It's going to star Tom Hanks as Walt Disney and Emma Thompson as P.L Travers! Wow!!
