Here is a great tin sign from the Falstaff brand of beer. Falstaff originated with the William J. Lemp Brewing Company which was based in St. Louis, MO. This brand eventually opened up multiple breweries throughout the United States, including New Orleans, LA, San Jose, CA, Omaha, NE, Cranston, R.I., Tampa, FL, etc.
The blue color used in this sign is unusual. Typically Falstaff used their white/gold/black color scheme with some occasional green and red signs also being used. This blue color is perhaps the only one I have seen with this color scheme. Circa 1950, this sign was intended for outdoor usage only.
