Those two pics are both the standard hardtops, or Victorias. A Crown Victoria has a large band of chrome up the sides and over the roof. Called "basket handles" by collectors. The brochure, and those two HT's all have the same roof, back glass.
The difference between a 1954 and 1955 is the Wrap Around Windshield known as a knee knocker, cuz banging your knee happened when entering/exiting.
