Parkway - Purity First

[UncleRahRay]

I am trying to find out something about the age and contents of this 11” tall bottle. It is thick glass - looks like a ribbed soda bottle. In addition to “PARKWAY PURITY FIRST” on the shoulder. An address is embossed near the base, “1707 ST. MARKS AVE. BROOKLYN, N.Y.” And on the other side, “REGISTERED CONTENTS 1PT.11FL.OZS.”

As best I can tell, the address is no longer valid. What the heck is it? Thanks all! This is my first post.

Looks to a be a soda bottle to me, but the contents may have been illegally brewed liquor from the prohibition era.
I found an article in old newspapers with details of a raid, here is one paragraph of that article.
Another partial article, I found amusing as they did find some soda bottles at the raid.
