It’s funny, the way I (we?) latch onto the cover designs of some books, but don’t notice others. This display of the different covers under which On The Road was published; of the US editions, I’m not at all sure which was the cover of the edition I first read:
![Jack Kerouac's On The Road](http://www.beatbookcovers.com/kerouac-otr/otr_usa_signet_1977_23rd.jpg)
But this is my best guess.
