FREE: A pair of Old Listerine Bottles. Halitosis is BAD. They Knew it in 1920

The listing, A pair of Old Listerine Bottles. Halitosis is BAD. They Knew it in 1920 has ended.

While I was nosing around I found some old bottles. They were filthy. I soaked them in laundry detergent overnight. Don't know much about antique bottles, so I didn't want to do anything radical. I imagine you could use efferdent or other denture cleaner, but as I am going to have a new gradbaby in the spring, I really don't need to be collecting glass. So they are cleaner than "fresh out of dirt, but certainly not pristine
One is 5 1/2" tall and the base is 2 1/4" across.
The other is 4 1/2" tall with a base of about 1 1/2".
I have tried for most of the day to date them and I think the closest I can get is from 1892 (when "crown tops" like these were invented) to 1920 (when screw-tops were invented).
While I was digging around, I found out a little about the product that I thought I's share.

"Listerine was invented in the 1800's as powerful surgical antiseptic. It was later sold, in distilled form, as both a floor cleaner and a cure for gonorrhea. But it wasn't a runaway success until the 1920s, when it was pitched as a solution for "chronic halitosis"— a then obscure medical term for bad breath. Listerine's new ads featured forlorn young women and men, eager for marriage but turned off by their mate's rotten breath. "Can I be happy with him in spite of that?" one maiden asked herself. Until that time, bad breath was not conventionally considered such a catastrophe. But Listerine changed that. As the advertising scholar James B. Twitchell writes, "Listerine did not make mouthwash as much as it made halitosis." In just seven years, the company's revenues rose from $115,000 to more than $8 million."
