I found in an antique shop in France the item seen below and would like to know more about the age and origin and material based on the logo/mark.
The seller told me it is from the Napoleon III epoch (~1850s) and pointed to the anchor logo on the top-left of the item with the letter N and D.
If it helps here is some more information about the item: I'm unable to determine the material of the frame. I don't think it is plastic but it feels a little bit like it.
The statue is, according to the seller, ivory-ish (in French he said: ivoirie). I can't tell whether this is correct or not.
From the state of the object I have doubts that this is 150 years old in addition I think it was (re-)assembled to its current form (recently). It is after all a present for the first communion ("souvenir de 1ere communion").
So, back to my question: Is this logo/mark something special or known? Is it a maker-sign? Can it be used to identify the epoch of that item?

EDIT: In the meantime I figured out that the figure represents virgin Mary. In addition to @RISwampYankee's comment, the logo could also be a family emblem or the one of a school.
