I don't think there are such books for sale. You can get a pile of paper of the same size. Then prepare a light box, which is a light bulb with glass on it, and then you can draw on it. Or there is no light box, as long as it can do this. Or on transparent glass. Then write the letter I on 1 paper, put this paper on the light box and put the second paper. Remember to align the papers at this time, then you can see the position of the letter I through the second paper, and then draw an L on the second paper. And so on.

I believe you don't understand, it's so troublesome, but it's a method of making hand-drawn animation.
