Of unknown origin, we believe this to be either of English or possibly Bohemian art glass made ca. 1900 or earlier.
It features lovely applied (rigoree) decoration done in iridiscent colors on a bulbous and ribbed base.
It measures 3 1/2" high and is 3 1/4" in diameter at the top rim. Overall diameter is approx. 4 1/4".
The condition is excellent in that there are no chips, cracks, etc., however, there are several air bubbles within the glass and one tiny one is a burst bubble right at the inside of the top rim. The photographs do show the air bubbles which range from very tiny to the largest that is about 3/16" long in a lozenge shape.
