Mystery Perfume Bottle!

I have an old perfume bottle I bought for $8. It has personal significance only because I bought it on our 4th anniversary (the flower anniversary).

Size is roughly 2 inches wide, three inches tall if the cap is on.

Cap: gold-tone, plastic (you can see black plastic on the inside), ornate sphere. at the very tip there is a tiny pink flower. twist cap. You can see a seam around the round cap.

Bottle: clear glass, marked with an underlined 16 at the bottom. glass seam goes all the way to the top, past the twist.

The flower on the front appears to be molded metal, painted pink. not sure if it came that way or the paint was added later? the metal piece is glued onto the glass (glue is now an amber color).

On the back, there is a small clear sticker, labeling the bottle "Remembrances" (another reason why it was perfect on my anniversary outing). No other markings that I see.

Very pretty. Might not mean anything to anyone but I love it. I would be forever thankful if you are able to provide the smallest clue on the age of this bottle, or anything else about it. I'm obsessively curious about it!
