The Caterpillar. One of John Tenniel's illustrations from the first edition of <i>Alice's Adventures in Wonderland</i> (1865).
The illustration is noted for its ambiguous central figure, whose head can be viewed as being a human male's face with pointed nose and protruding lower lip or being the head end of an actual <a href="//commons.wikimedia.org/wiki/Caterpillar" title="Caterpillar">caterpillar</a>, with the right three "true" legs visible. ("And do you see its long nose and chin? At least, they <i>look</i> exactly like a nose and chin, don't they? But they really <i>are</i> two of its legs. You know a Caterpillar has got <i>quantities</i> of legs: you can see more of them, further down." (Carroll, Lewis. <i>The Nursery "Alice"</i>. Dover Publications (1966), p27.)
