This offering is for a Zodiac Sagittarius Button. It is made of brass and has a sturdy loop shank on the back. It is listed in the BBB on page 405. It does have a spot of verdigris on the back and a small discoloration on the front at 2:00. I think it can be cleaned, but I am leaving that up to the new owner. This is a great button for your collection. I believe the age of these buttons are 1040's.
