I use to be irritated by clown jokers. I thought they should have jesters on them. But through the years, my sensitivities have changed and I'm now a big fan of clown jokers. Which is good since I have a ton of them. (BTW, even though this article was just published in Feb, I'm updating in April since I added and rearranged the clown jokers.)
This first set is classic old clown jokers of which three are on the Joker Poster printed by the Playing Card Museum.
Here's more classic old clown jokers or modern ones in the vintage style. The two clown heads in the middle row are from a Steamboat deck made by Novelty Playing Cards in 1935 (which I know because he's 5H on the Joker Poster). Notice that there are drumming clowns but my rules are that they go in the clown section, not the drummers.
