The story begins: "There was a hill"
You lift the flap and it says, "that was a bear"
The next page: "That climbed a tree"
Lift the flap: "that was a trunk"
Now if I could just get publishers to stop letting books go out of print. I found this copy at a thrift store, so they are out there. I've also seen them on Amazon.com and Half.com for reasonable prices.
I am reading this one for my grandchildren.
