It's a reworking of a memorable Murphy Anderson cover from the sixties. As you can see, José's pencils were amazing and I tried very hard to retain as much of the middle tones as I could in the inks, especially the ape fur.
He improved the layout by moving things around a little and he made the ape a bit more realistic and a little less cuddly.
Here's Murphy Anderson's cover from 1965. This was the kind of image that could really warp a young mind, especially one that's only recently recovered from the sight of those flying monkeys in The Wizard of Oz.
