Every ceramics manufacturer / factory and even studio potter needs a maker’s mark so there is no question as to who has made the piece of ceramics / work of art / chipped china you are holding.
My particular mark is inspired by the Hermine (Ermine), the heraldic symbol of Brittany. https://en.wikipedia.org/wiki/Ermine_(heraldry)
The pictures below illustrate how my mark is derived from the original heraldic device.
