Antique Water Dropper Asian Design Possibly Korean

Beautiful Vintage or antique - exact age not known to me.  Thrift store purchase, I do not know the history of this piece.  Possibly Korean? 

Blue bamboo, flowers, sprig decorations.  Signed or marked on underside.  Grayish color glaze with blue decorations. 

Approximately 3 3/4 inches across.

Octagonal shape, 4 very low "feet"  just barely elevate it off surface. 

This is not my area, I just liked the piece when I purchased it.  Please see photos. 

CONDITION:  No chips or cracks.  Does have glaze crazing.  Some grime in the dropper holes.  Bubbles, bumps, specks, and sandy areas in the glaze.
