The 1st printings of King's 1st two paperback books did not have his name or titles on the covers. It was a marketing ploy used by Signet to capture a readers eye- What, no title or name on the cover? Who is this author? I remember reading in interviews that King was NOT happy with this choice, but went with it anyway.
Notice how on the Lot cover there is no image or mention of vampires like on later covers? This is what was so cool about this book, you didn't even know what was going on until 2/3rds of the way thru when it is revealed that the evil is vampires!!
