In the middle row above, right side, there is a clown head from the joker poster. He is row 5, position H on the poster. A USPC jokers made for the Kreko Club. 1936. I think that is what this joker is but as I research it, I realized that I have more checking to do. I just read Steve Bacon's comments on a similar looking one next to one of his products for sales in Two for His Heels at Rubylane.
Here's another pair of jokers that I just added to the clown head section. Arguably, the jack in the box clown head should be in the jack in the box subsection of the jesters on the stick section so that all the jack in the boxes could be in one place. BUT, since a clown is NOT a jester AND the clown jack in the box is paired with a clear clown head, it is in this clown head section.
And here is a photo of my Jack in the box subsection of the jesters on the stick section. There are also some dog jack-in-the-boxes (sixth page). Note also that bottom row left below is also on the Poster in the 2B spot. He is USPC for Barton Playing Card Co, c1960.
