Clifford in CLIFFORD'S HALLOWEEN

Here is Clifford, the Big Red Dog, from Norman Bridwell's Clifford's Halloween. The text reads "An Indian?" Clifford is shown in a feathered headdress of multi-colored feathers. In his mouth is what might be a "peace pipe" and he wears a white sheet, presumably meant to be a robe of some sort. Note, too, the "face paint" and the way his eyes and eyebrows are drawn. And the raised paw.... Is he saying "How?"
