I have been looking for vintage buttons for two years and this summer hit the button Bonanza! A friend that is an antique dealer had bought out a Vintage Button business and now those buttons are mine. All buttons shown are from that collection. 1. 2. 3. 4. 5. 6. 7. And a delightful grey tweed with classic coat buttons. No edging on back. Side view with one upper button. The measurement is in cm. This is slightly over 11 inches, making this hat a medium.
