This is an over-sized book [9.5 x 10.75 x 1.25] with 28 pictures to change by pulling the tab. Each letter of the alphabet asks a question and gives a clue. When you pull the tab, you see the answer. For example "What has a baby called a calf, gives us milk every day and begins with the letter C?" What a fun way to learn the alphabet for it encourages child participation.
