Here is a Old Musty Ale Flange Sign from the Robert Smith’s & Sons Brewery located in Philadelphia, PA.  This Old Musty Ale Flange Sign is from between 1882 and 1887 and is in excellent condition for it’s age.

This Robert Smith’s Philadelphia Old Musty Ale Sign is approximately 10″ X 14″ and is made of steel and porcelain enamel paint.  It is double sided with the same advertising on both sides and doesn’t have any sign makers markings on it.  Signs like this one would have hung outside of taverns and hotels to advertise the Robert Smith’s Brewery Old Musty Ale which was a flagship beer that the brewery brewed during that time.
