This is a clear glass cruet with stopper made by U S Glass in 1902.
The Peacock Feather design features a herringbone design above a beaded oval and it stands at 8.5 inches tall and holds 7 ounces,
It is an original piece and was produced in the United States during the Early American Pattern Glass era.
The inside of the spout that touches the stopper is rough, all other marks , I my unprofessional opinion, are from manufacturing. Please see photos.
