Last night Christopher Erkmann from HarperCollins's art dept showed me the coolest cover ever for the mass market edition of Kevin J Anderson's The Last Days of Krypton which comes out this September. Remember those holographic buttons when you were a kid. You know the ones where if you change the angle you can see an eye wink, or skeleton walk. Well, that technology has finally been updated for the 21st century by Extreme Vision and its called lenticular 3D. There's serious depth when you look at this cover straight on and then when you tilt it back and forth you see the Superman logo zoom out of the explosion right at you. If you're going to be at San Diego Comicon make sure to check out the cover flats they're giving away since this photo doesn't really do it justice. Rumor has it there's another super secret advance holographic prototype cover coming up from Harper (shhhhh). If the first step in selling a book is getting someone to pick it up, these books will sell like hotcakes. Actually, hotcakes aren't selling so well these days, so they'll sell like something that really sells well. Like Beer?
