Whereas I see, in the center, a big-nosed, small-chinned goob, with an immense booger hanging from the nostril, and, at the left, a hand (presumably the goob's) holding a handleless pitcher. On the right, I see an individual with a more rounded nose and heavy brow-ridge.

All of which suggests to me, that there's less here than meets the eye.
