This is a vintage set of brass shank buttons.  There is an attractive floral design with a scroll pattern with a mirror back.  They measure approximately 18 mm or .71 inch, almost 3/4 of an inch in diameter.  They would make a definite statement to any piece of clothing, hat, scarf, or others.  Please see all pictures for a complete description.  These beautiful buttons are becoming harder and harder to find.  Thanks.
