Once in a while I will come across an object and think "I like that, I like that a lot". I may not necessarily want to buy it but I just want to look at it. This poster has that effect on me.
As you can see, this poster is advertising Excelsior Ginger Ale from the John Klee Bottling Company of Dayton, Ohio. According to the US Library of Congress, it dates from August 29th, 1885. The ginger ale was sold in the Joseph R.Peebles Sons chain of grocery stores in Cincinnati, Ohio.
Not a lot is known about the John Klee company apart from the fact that John Klee himself was an immigrant from Germany who founded the company in 1866 to manufacture ginger ale and sodas. The company closed in the 1930s.
