New2grammarKhoff, if you don't mind, what's the meaning of classic here? well-known?
Hopefully, Khoff will put it better than I can. I've tried to explain it before and failed miserably.
To me, "classic" = "iconic," but the dictionary definition of "iconic" doesn't seem to be in my favor. Well-known certainly applies. Let's say, something so well-known that everyone immediately thinks of it as the best, most perfect, example of a particular class or genre.
Michelangelo's David, or DaVinci's Mona Lisa, or Van Gogh's Daisies, or Beethoven's fifth, or Sousa's "Stars and Stripes Forever," or a 1964 Mustang, or the Eiffel Tower, or Orson Welles' Citizen Kane, or Mae West's "Is that a pistol in your pocket, or are you just glad to see me?", or the wife's reply, "Not now dear, I have a headache."
