There are even more now. Always a sucker for interesting cover art, I was pretty much delighted when I found this collection of fake book covers a month or two ago (maybe via Maud Newton? I'm not sure), and am delighted again to have revisited it (via Bookslut this time, for sure) today.
Of course the covers are by turns gorgeous and silly and wonderful, but I think the thing I like most about them is the fact that they (by virtue of being imitations but not quite parodies or even derivative works) do such a wonderful job of illustrating and commenting on the conventions of cover art.
Only sort of related: There's nothing quite like finding a blog you love long after its owner has stopped updating. Judge a book is gorgeous, but I'm pretty sure it's over.
