Vintage Navy Blue Straw Hat by Mr. John.  The color looks a bit light in the pictures.  It is navy.  There is no materials label, but it looks like straw to me.  This came from Tat Saunders Shop in the Ritz Carlton Hotel in Boston.  Inside circumference is 21 3/4".  Brim is 3" wide from underneath.  Has a fancy inside band and a lacy "sub" band.  In excellent vintage condition.  See images to assess.         A660815
