This is a signed clear glass perfume bottle that changes color based on the light. Right now it’s a blue color. If I shine a black light on it-it turns purple. It does not have a stopper. I have added a picture of the bottle when the color changes. The bottle measures 2.75 inches across the widest part of the bottle and is it just over 4 3/8 inches tall. The bottle has what I think is 1991 engraved on the base with 975 across from that. I do not see a signature or any other markings. The bottle has no chips, cracks, or other damage.
