Big Book of Halloween Entertainments, 1944 (by bohemea)
Here’s an excerpt from the Novelties section:
My Halloween Mask
I’ve made a Halloween mask
With jagged teeth and ugly eyes;
I’ll tell you what I play to do
But sh! It’s to be a surprise.I’ll sneak behind Betty Jane
And then behind Sally, too;
I know they’ll all be scared to death
When I hold this up and yell, “Boo!”[Child holds mask in his hand. As he recites last line, he places it over his face.]
