Models in this range (sub-series 680/681) were characterized by traditional standard equipment additions and by emblems containing a Cadillac shield encircled by a laurel wreath, which appeared on the hood and center of the deck. Fleetwood designations, in block letters, were also found at the right-hand side of the deck. The Brougham had the wreath-style medallions on the roof pillar, along with Tiffany scripts in the same location to identify this extra-rich model.
