Mount Royal & Maryland Avenue
From about 1920 to 1933, the Lambert Motor Car Company operated from what I can tell from a dealership at the corner of Mount Royal Avenue and Maryland Avenue. In 1933, Lambert was advertising the sale of Hudson’s and Essex Motor cars. Around the time the name of Lambert was being used in Baltimore, the name Lambert was noticed as being a dealership in Hagerstown. Not sure if there was a connection, but I’ll keep researching.
