Please help me identify the characters on the seal (Characters identified: 知惠子) Please help me identify the characters of the seal (again).
My friend identified one of the characters as ’和’ but she's not sure with it.
The characters are 知惠子, which point to a Japanese name probably pronounced as Chieko (ちえこ).
