Les Fleurs de Mal

Recently, I was quoting something from Charles Baudelaire's Les Fleurs du mal, from a version in which the English translation is at the front of the book and the original French follows.

After typing out the English version, I decided to take a look at the French version to compare them; to see how I would have translated the French.

Well... as you can see, the pages in the book jumped from 190 to 239 and the missing pages were not to be found elsewhere in the book. There were, however, pages of 239 through 270 are duplicated.

It's a first edition printing of the book (as best as I can make out) but I was told that it likely isn't worth that much as a collectible.
