Henri Hamm - A great button designer

Have you heard of Henri Hamm? I hadn't, until I discovered his buttons at that fantastic button exhibition in Paris. I took a picture of his name to learn more about this fascinating figure. To my surprise, there was not much about this great man on the Internet, not even a mention on Wikipedia!

When I saw this, I immediately decided to join and published a small article about him, as surely he was a great figure, worthy of an article.
