Check out the cover of Violent Earth. It's hard to capture its full awesomeness in photos, but I'll try.
Firstly, there's the crumpled plastic texture of the lava background. This is a very tactile cover that begs to be handled - a good selling point for a coffee table book.
The lettering on the cover hasn't been neglected either, with spot gloss for "Violent" and a metallic gloss for "Earth". This typeface is also well-chosen, as the bold, capitalised sans serif stands out against the busy, textured background.
