DescriptionNeon letter S is housed in a metal cabinet with a plexiglass font panel. Southern Sign Supply, Inc. offered a full range of electric sign supplies from substrates to paints and vinyls. In the late 1950’s, SSS was bought by Lloyd Gerber who moved the business from Monroe St. in Baltimore City to Glen Burnie, MD. By the mid-1960’s the business relocated to Pasadena, MD. The last change of ownership came in 1989 when William and Anne Pearce purchased the business. However, with the decreased demand of vinyl letter cutting plotters and ultimately lower margins in vinyl over paint, Southern closed in early 1996.
