Lot of 3 small bud vases.  I would consider these Mid-Century Modern or Retro style.  The glazes is an Ombre style with an aqua blue at the top gradually blending into olive green at the bottom.  The vases are not signed, nor do they have a makers mark of any kind.  They measure 4 3/8" - 4 1/2" tall.  There are a couple of small manufacturing imperfections in the glaze that do not really affect the overall appearance of the vases.
