Mei (signature) : mumei
Length : 7.75 cm or 3.05 inches × 7.29 cm or 2.87 inches.
Jidai (era) : middle Edo period.
Special feature : On the Mokko style nice colored Syakudo nanako plate, Bamboo grass and 2 shishi dogs are　engraved highly.
That's remarkable a motif because of the comparatively unusual combination.
On the back, the bamboo grass and two shisshi dogs are engraved with gold color too.
We can see delicate work on the pattern of the shishi dogs' body and the golden eye of the black one.
