Mabel drew this with the aid of a photo of a model of a T-rex. She drew the big eye first then the head around it. Then the teeth, the body, and an accidental tail that she later extended upward (on the right side of the drawing) The line floating out to the left was originally an arm, but then she drew two little short ones in a more appropriate spot.Then the little legs at the bottom came next. She made two at first but then added the others in two quick slashes. Finally, “Oh it needs another eye!” she added, and then added the other eye.
