What can be so bad they'll sue you for putting it on a public website? If that's the case, you'd be as well to keep it at home and never take it out to a gig, because people will still see it then.
And if the markings are 'unique' then they're one of a kind, not belonging to anyone, so you can't break the law if they're unique.
Yes, I am bored. Anyway, congrats on the guitar. Very classy looking.
