Those ads are about as good as anything you will find - from them we know the company dates to 1920-22
The question is whether the bottle is machine made or not - hard to tell from your photo. If the mold seam runs to the very top of the lip / mouth than it is machine made. Regardless, the bottle is very plain and the label does not have much of an antique or vintage look to it so I would give it minor value (as in less than $10)
Thanks for posting this.
