Probably dating to the 1950's, & measuring 13/16" x 11/16" NBS Med, here we have a wonderful example of the artistry of the porcelain Arita buttons made by Toshikane China. This foo dog was on a card of 6 and has the original paperwork with it. It has a trademark and "JAPAN" on the back. It has a self shank. You are buying one button. I want to keep the paperwork with the other 5 buttons. Excellent Condition! $75
