What's the first book you remember owning?

[kboleen]

I was reading on Ain't It Cool News this morning about a Where the Wild Things Are movie when I realized that was the first book I remember really owning. Where the Side Walk Ends was another.

What book does everyone else remember owning? Now, I'm 42 years old with no children of my own so my children's books are something I haven't thought of in a long time. And I imagine the younger of the community will remember easier.
