These jokers come from 2 decks, that were published by the Monty factory in the Netherlands. The decks were printed by B.V. Rhoon printshop in the early 1960's. Each card was given away with a pack of chewing gum and a complete deck could be collected by exchanging cards with friends and of course....chewing a lot of gum yourself. 
You can imagine that these jokers are extremely rare to find. The first 4 are from the "vintage cars" deck and the last 5 all belong  the "modern cars" deck.
