The first seated joker is published by John Waddington Ltd from the UK.
This next one doesn't have a wand or a jester hat hat but he does have has big ears, a ruffle around his neck, and contrasting colors. Is he a jester? I think it's close enough for this section since he is really sitting. He might be in the process of putting on his shoes.
If you have a reaction or observation to one of these jokers, or if you know something about their origin or design, please share it in the comments below. Although my numbers of jokers are high, I feel my knowledge about them is very low. Please help.
