I get that question a lot. I do not worry about it. There's plenty of similar fan art selling around and I haven't noticed any actions taken to shut them down. I wouldn't reproduce anything under a trademark (for example, Baby Yoda), and as far as I know, human faces are not trademarkable.
I think it depends on how the work is produced for celebrities. If it’s a mass produced product and not one off artisan creations, OP might run into problems
They look to be making several of each person.
I imagine nobody is going to bother with them until it reaches a certain scale.
Making several is not the issue, I believe. You could make several slightly different hand crafted statuettes, it’s the mass production of one likeness that’s the issue as I understand it.
Could it be that he does not use the name under the likes of Elon and Jordan, so it could be left for interpretation?
