Just added from comments - Oct 2020:
Latvanyterkepek - Hungarian Jokers
But not this one: Greetings > > http://szlemik.bloog.pl/ - Andrzej (email@example.com) - since the URL doesn't appear to be jokers. I probably should try the email...
If you'd like to be mentioned, comment here and I'll approve it. I would appreciate it if you would also mention my little collection.
There's an update to this article started in early 2020 about other online joker collections.
