Here is a National Beer Lighted Sign from the National Brewing Company located in Baltimore, MD.  This National Beer Lighted Sign is from the 1950’s era and is in very good condition for it’s age.

This sign is approximately 30″ wide and made of reverse-painted glass mounted in a back-lit metal body.  The lettering on this sign reads “National Beer” and “Quality so good you can taste it!”.  Sign like these would have been display as a bar back display or hung in tavern windows to advertise National Beer and National Bohemian Beer (Natty Boh) to patrons.
