I do not know what the text is in full, but I think it relates to Mr. Rockefeller's use of wig as a disguise:

Basically it seems he was quite unrecognizable in this disguise. So this plate seems to be a search order for Mr. Rockefeller and warning that he might use a disguise.

I can only speculate, but it all seems rather clandestine. If I'd be forced to make a guess, this is by some powerful world wide enemies of Rockefeller, maybe some counterforce of Free Masons who Rockefeller was in cohorts with. They distributed these leaflets in secret everywhere in the world in their effort to catch mr. Rockefeller.

Of course when some swamp dwelling Finnish people receive such a plate containing mysterious language they can't comprehend, they will not use it but toss it to the fields. With the impenetrable logic that maybe it is some secret runes that make the plants grow stronger.

Anyway, this is quite an extraordinary finding.
