Here we have an Antique 25 pcs set of 19th century Kutani Imari Arita porcelain.  There are 12 Cups & 13 Saucers.  The pattern is blue & white with a transfer pattern that is hand painted over in color. The pattern has butterflies, flowers , pagodas , people & other.  The pieces have some wear to the paint.  One cup has a spider hairline at the bottom of the bowl, otherwise they are in good condition for their age.  My guess on age is late 1800's or early 1900's.  The saucers have a 6 character seal or mark on the bottom.
