I found this bottle and was curious about what it might be and when it could have dated back to?
Thanks for posting. It would be helpful to know what markings if any are on the base of the bottle. Also, I cannot quite make out the text on the body of the bottle.
One can say, in general, that this is a mid 20th century, machine-made aspirin or other medicinal pill bottle. Perhaps I can be a bit more specific with your further details.
I pulled this second photo from your other post. From this we an say Owens Illinois manufacture.
The bottle still has the cotton in it.
