Here are a couple of illustrations from Stantoons #1, by Eric Stanton. The bit of story that goes with these is below:
“Whip her calves. No more than forty, mind!”
She receives precisely thirty nine harsh slaps of the wire-stiffened crop across the backs of her calves. The fatly muscled flesh indents deeply under the blows … and she can only weep, silently. Not only can she tell them nothing, because she remembers nothing, did nothing, but right now her gag won’t even allow her to tell them that!
