You can't judge a book by its cover...or can you?

The powers that be (other readers) wrote of the cover to Salinger's novel:

Catcher in the Rye's pallid cover, adorned only with seven multicolored bands in its upper-left corner, is not what one would call eye-catching. Its reverse side lacks criticisms or reviews of any sort; in fact, it is bare of anything except a copyright date. Human beings are advised not to judge books by their covers, rather that they should look further than the obvious and try to apprehend the implied meaning.

Thoughts/comments:

1. What do you think of the book's cover? What kind of purpose does it serve? Is it indicative of something?

2. If you were given a chance to design another cover for the novel, what would your cover involve? Describe your cover.
