This metal button is a nice example of a simple Art Nouveau style floral design. It would have been fun designing all the patterns for buttons and I can imagine in the late 1800s and early 1900s that someone drew with pencil on paper squiggling different lines until they achieved something they were happy with. No computers back then! Then the making of the moulds; how clever. This button measures a little over 2 1/2 cm.
