The kindle editions have boring covers though.
It’s the same with everything else these days. No one wants to pay real artists anymore. 😦
Edit: I looked up the series original cover artist, Richard Hescox. He’s still active so it looks like there’s no real excuse for breaking tradition with the cover art.
Maybe it’s a money issue where reprints or digital editions are concerned? The most recent editions of The Hitchiker’s Guide To The Galaxy books I’ve seen have horribly bland covers too.
