The Beer Can and The Growler

 

 

 

 (right)  Tho' not as common, an example of a bottled beer being advertised as a "modern" growler.  The large (18" tall) half gallon bottle, often called a "picnic" bottle, was used by a number of Eastern and Mid-Western breweries before and after Prohibition. 

 

 Unlike the canned beers advertised above, the picnic-bottled beer was like the beer from a true growler in one other way- it was not pasteurized, and so had to be refrigerated or consumed soon after purchasing it.  Thus the reference to "Real Draught Beer".
