The one with the top down is actually a "Skyliner", a retracting-roof hardtop (See below, notice the difference in the trunklines.).
Neither one had "Sunliner" or "Skyliner" badged anywhere on them.
Nevertheless, they were still being called that as late as 1959, even in the Ford ads. The earlier Buick two-door hardtops never had "Riviera" on them either, but they were all still called Special, Century, or Roadmaster "Rivieras."
