When asking my question regarding a possibly antique object I reduced it to asking for the meaning of the logo and (if any) its historical meaning.
In reality I would have preferred to ask for more information. Material, usage of ivory for this kind of object, how to determine whether it is ivory and questions like this.
Is, in contrast to my understanding, history.SE the right place to ask this kind of questions?
If not, should it be?
If not, would it be worth launch an antique.SE where people can ask questions of antiques and their origin (not their value)?
