This is an Ivy Boy button badge by Illustrator Kazuo Hozumi. It was a promotional item from 20 years ago when he was selling Ivy Boy dolls and picture books at VAN shops. There were few made, so it's quite rare now. It's a standard 32mm size. The image shows a comparison with a blazer emblem. It's a new, unused item in very good condition. For those who appreciate its value.
