Antique Royal Dux Porcelain Japonaiserie Brush Pot

This is a fabulous antique porcelain piece made by Royal Dux of Bohemia. I believe that the piece is meant to replicate a carved Japanese brush pot, although I cant be certain. It appears to be a trinket box or a humidor bottom. I believe that it is missing it's lid. I haven't found evidence of Royal Dux having made humidors. It features a Japanese lady in raised relief along with a cat and vase at the front, trees at the sides and mountains at the back. This piece is oblong and I dont believe that it ever had a lid. It is impressed with the numbers 5418 and 40, hand inscribed with the number 53 and marked with the Royal Dux Bohemia raised E pink triangle, used between 1860 and 1918. It measures 4 by 5 across its top and 4 1/8 in height. It is in very good condition with just a tiny fleabite type chip to the top edge, very negligible.
This is an unusual example - I havent been able to find a similar example anywhere. Wonderful display piece, great for the Royal Dux collector or for someone with a collection of Japonaiserie.
