Japanese Tea Set

 Inherited Japanese tea set , don't know anything about it, but guessing early to mid 20th century. Six cups, saucers and plates. Two pots and i'm guessing a sugar bowl? Has the picture of  a Geisha Girl at the bottom of the cups when held up to the light. The picture of the girl is MUCH clearer and detailed than the photo (best i could get!). Has "Hand Painted Japan" on base of pots etc. with a Japanese type symbol. I would likw to know the value of the tea set. Many Thanks.
