Martin Ringdahl Filling Station - 1932
1949 St. Johns (corner of St. Johns and Elm) - Highland Park, Illinois
Demolished or Altered

          This was a Mobil-Socony filling station and garage.  By 1937, it was already altered and expanded into an auto showroom.  There have been many alterations since, and it is doubtful that any of the original structure still exists.
