I was sent this photo by Rick Smith of http://www.bpinorthavenue.atspace.com/

This storefront Little Tavern was located at 1 East North Avenue, Baltimore, MD
The opposite corner was once home to a similarly styled White Tower.

You can make out in the White Tower photo part of the sign of the Little Tavern reading “Hamburgers”

Here’s another photo of this location, from 1960s Little Tavern company documents.
