It has a décor in enamel dark blue and red, as little hearts attached to cords painted hand free and fired, there are some bubbles in the hearts and lines, the pattern is very art nouveau. It is not marked and the pontil is very smooth has been polished letting the inner layer of clear glass. The blank seems French late XIX century with the characteristic hollow stopper that fits in the tri-cornered rim.
