Vintage Japanese Moriage Ashtray

Vintage Japanese Moriage Ashtray. This bright porcelain Japanese ashtray may have been used at one time for cigarettes as there are a few slight age marks on it, but I have only known it to be in my mother's china cabinet which she filled with special collectibles. As my father fought in the Pacific during WWII, my mother collected several items from Japan and China in the years after the war, so I am assuming this was made circa 1950's as it has a brownish/orange patent mark on the back of the ashtray. It is marked with a symbol, stating "MADE IN JAPAN", PAT 105665. The first digit of the patent number is worn, but through research I found it is the number "1". The round ashtray is 5 1/4" across and approximately 1/2" deep. The rim is bright orange and marked with gold and brown. There are three indentations for resting cigarettes. The inside is painted in moriage style (raised paint) with a design of flowers and twigs in yellow, white, and green on a white, blue, yellow, lavender, and green background. The paint is bright and there are no cracks.
