So I’ve known it was an old copy of the book. It’s hardcover and it’s old, but today I checked the copyright date and it’s from 1965 which was the year Dune was published. I don’t have any dust jacket for it.
But I think it’s a first edition.
How cool is that?
I don’t remember where it came from, it may belong to one of my older brothers and it came into my possession through the boxes of their books. But it makes a nice focal point of my book shelves.
