No marks of maker or origin, except a gold mark on the bottom that appears to be the initials EO.
THe blue of this vase is a peacock blue that looks rather similar to the blue satin glass pieces of Tiffin glass, US glass maker, but I could not authenticate a maker for this piece.
In fair antique condition, this vase does not have cracks or breaks, but does have some fleabites, particularly around the inner ring of the top rim. Also, the piece needs to be cleaned, but I will leave that task to someone who is expert at cleaning this satin type surface. Some bubbles are also present in this hand blown piece.
Please review photos to confirm condition.
