Since 1959, Miami has been the home of a three-story tall electrically lit sign of the iconic "Coppertone Girl". Its location has been shuffled around a lot over the years, but it currently can be found at 7300 Biscayne Blvd.
The original Coppertone logo was an Indian chief with the slogan "Don't Be A Paleface." Fortunately, at some point the company decided they could do better. The story has been told that they'd planned to use an adult woman in a bikini for the logo, but the owner's wife disapproved and suggested making it more innocent. If true, I would expect the dog would have to have been a Great Dane or a Mastiff or some such.
