I think the point is that the cover is never guaranteed to accurately represent the book.

Quality of cover =/= quality of book

Yeah, the point of a book cover is to sell the book…
The point of a book cover is to cover the book.

That’s one of the purposes of a cover, you could achieve it without any design effort.

But that’s not the point, not the main purpose of a book cover. Your previous poster is right, the cover is advertising the book.

The “cover art***” sells it, then. They were trying to be funny I think lol
That’s the point of a dust jacket.
I thought the point of the dust jacket is to make books look shabby when they get crinkled and torn, so you can take it off and find a perfectly serviceable cover underneath.
