Nightmare fuel: Covers of two "children's" booklets with clowns

These two staplebound booklets were inside a box titled "Little Dots for Little Tots," published by The Platt & Munk Co. in 1939. Both booklets feature connect-the-dots puzzles. Piffle is the name of the clown. Or at least that's what he says his name is. We know that some of these clowns can go by several names.

Piffle's Pastime Dot Drawing Book

Piffle's Mother Goose Dot Drawing Book
Horrifyingly, it's not even clear that Mother Goose realizes there's a clown behind her. Just imagine: You're minding your own business, flying high on a nice goose. And suddenly you turn around AND THERE'S A FREAKING CLOWN BEHIND YOU.
