The jaguar was my favorite animal when I was a kid. At the Natural History Museum in Milan, Italy, where I grew up, there was a wonderful display with a jaguar fighting with an anteater. I was fascinated by it. Anyway, when I began planning the toucan spread for the book, with a scene from an Amazon-like forest, I decided to draw the picture of a jaguar in it. As reference, I don't usually look at photographs as I prefer to use old paintings and prints. I like to see how other artists have interpreted the same things I am about to draw. So, here are a couple of pictures I found, the preparatory sketch, and the final drawing as it appears in the book.
