The Potomac Diner was originally located at 930 S. Potomac St., Hagerstown, MD. It opened in 1942. By 1945, the address was being used by an Insurance company and the diner had moved to 934 S. Potomac St., what had been the site of the Hagerstown Auto Exchange up until that point. In 1977, it became Barbie’s Place, and the address was 925 S. Potomac.
As mentioned in the previous post about the Dixie Diner, the manager of that establishment, Earl Shetler, switched over to manage the Potomac after the Dixie lost its land.
This is the only photo of the original diner I’ve been able to find. It looks like an on-site construction to me, but with only one poor quality photo, it’s hard to tell. Looks like there may be neon clocks on the ends.
