Estimated age of the vase is who had a porcelain and decorating studio in Fischern, Bohemia (now Rybare Czechia). Found on examples of hand painted and hand decorated porcelains that are signed by artists who are most likely American China Painters.
They also had a decorating studio in Limoges, France. My speculation is that this overglaze green stamp was provided for application on the whiteware after decoration with the flower pattern that was copied by the artists. This appears to be the stamp of the manufacturer of the board/paper used by artists for their creations.
