Mr. Boh is the iconic mascot of the long-closed National Brewing Company of Baltimore, Maryland, whose flagship beer had been National Bohemian ("Natty Boh').
Office space, retail, and condos now reside in the former brewery —located at the at the intersection of S. Conkling and O'Donnell Streets, in the Canton neighborhood of Baltimore— rechristened Brewer's Hill. At night, the illuminated Mr. Boh winks once every 47 seconds (at least as counted by Baltimore beer blogger and author Alexander D. Mitchell IV).
National Bohemian is still produced, but not in Baltimore for quite some time. The international conglomerate SAB/Miller produces the beer as a contract brew for Pabst Brewing, in its Eden, North Carolina, plant. Baltimoreans will tell you that it definitely is not the original recipe, hon.
