Japanese prints
 

Found in the family archives of Japanese prints size 15x21 cm material similar to the fabric in small scar, a paper substrate, is easily separated. I read online that this is likely to rice paper.
Please tell me the technique these engravings, which period could be created. maybe someone knows the author. Just want to know the commercial value. I'm not very good in Japanese art.
Thanks in advance to ALL.

Good processing,no wonder the East gather.With HC.
