Early 20th C. Japanese Water Color, Unsigned

Mexican Peso Price.  This is from an Estate that contained a number of dated and signed water colors from the early 20th C. in Japan. The signed ones are by Chas. A. Wirgman, Jr and dated 1904. This one is unsigned. This measures 25" by 19".   There are 5 of these 100+ year old watercolors .. We have backed them all with acid free board but the matting is antique and needs changing to prevent further damage to the water color paper.  This painting has good color but there are some age stains to the upper sky area of the image.
