I'm with Roman - I would tell them you'd like to put the label on it. Let's face it - it should be on there. If it's no where to be found or they "forget", then just let it go. But, if you are able to, get your label on it and return it to whomever owns it now. It would be a shame if it was out there an no one knew it was made by a family member... If I had it, I would want to know that fact, and I would be honored to have the label placed on it. (Then I'd flip a coin - you win - you get it back - I win - I get to cherish it.) JMHO
