Found this in a bunch of old bottles and really can't find any real information about it online or here on the site although I have found examples of "Jockey Club" bottles. It is a 10z. bottle with the word "Jockey" of the front & back. On the bottom, there is Miami / Fla / 10 oz. / A 50 / and a keystone with a J in the center. This mark indicates that it was made by Knox Glass Bottle Company, and was used on containers made at their Jackson, Mississippi factory location (1932-1953). I can find no other marks anywhere else on the bottle. My questions are what were the flavors of Jockey; who made the drink; during what era and where else other than Miami, Florida? All comments welcomed. Many thanks.
