Beautiful set!  Imari in rare and beautiful quality.  Likely from late Edo Period.  Porcelain with marks imitating Chinese marks of the Ming period were made at the Arita kiln during the 19th century and possible both earlier and later.

Offered are 12 saucers and 12 tea cups.  The plates are approximately 5" inches in diameter. The tea cups are 2 1/8" inches tall.  Only one tea cup has a small chip and two plates have one small chip.  Overall, amazing condition for such a large old set!
