Hey, Hungarian here.
What's actually going on with Jucika's copyright, is that copyright doesn't really work in a way where every single thing is registered in one place. You have copyright to anything you create, but you don't call up the copyright office every time you create a new character or strip, the law only comes into effect when someone copies your work and you make a complaint.
Now, technically, you can also give them a call and add your work to an official registry, but Jucika is from the 1960s, who while everyone knows it exists and someone has a copyright, it wasn't registered into the modern system, or at the very least was never digitized.
This doesn't mean that 'no one knows' who holds the copyright, it's just that the main copyright office (whose job is to handle disputes, not keep a master register of all intellectual property that has ever existed) does not know.
Instead, copyright is handled by at the 'preventive' level, I guess is the best way to put it. Which is to say, the original magazine had legal filings that Pusztai Pál gave them permission to copy and print his work, and anyone who since has been republishing Ludas Matyi or the comics specifically are expected to similarily seek out the rights holders and get legal permission.
In short, the way to figure out who holds the copyright is not to contact the copyright office, but to contact the people currently republishing these works officially, as they would be the ones who have the legal paperwork that later the copyright office would need to take a look at and determine if it's valid or not.
(Also before anyone suggests, yes, I already told this to the fan artist privately and they may or may not be on it, I'm sure they have other stuff on their plate than untangle a 60 year old legal mystery.)
To be clear by the way, our government is largely a joke, but I felt I should point out that in this particular instance, it's not their fault.
No one could keep a full registry.
