Antelope porcelain creamer

We bought this creamer on 2004 to Dorita. I do not remember the price because Sergio was who purchased it. He loves sculptures and this is so figurative, since besides the shape it has relief in all the surface. It has impressed (third picture) Ges. Gesch. : abbreviated form of Gesetzlich Geschutzt: legally protected, patented, copyrighted, Deponiert, 5220/1 and Germany. I am pretty sure it is Royal Bayreuth because they produced this type of creamer and they used to marked with Deponiert (REGISTERED), very usual about 1880. RS Prussia and Royal Bayreuth were the main producers of this type of figural tableware and some times it is not easy to say the exact origin of a piece since not all were marked.
