Of the repackaging of classics there is no end. The latest outburst is Vintage Classics and its second line-wide overhaul in a couple of years. This time they're obviously aiming to make a dent in Penguin's market dominance by putting out a whole lot of older, public-domain classics like work by Dickens, Melville, James, Austen and the like.
One nice promotional touch is the selling of some of these older classics with well-chosen limited-edition contemporary "classics" from Vintage's line. The pairings are mostly pretty good, and the matching covers are rather nice.
The best may be the combination of Oliver Twist with Trainspotting (both stories of the urban criminal underclass), the covers featuring animals which play minor but memorable parts in the stories (Sykes' dog and the cat which kills Tommy with toxoplasmosis).
I also like the ligature in the text on the Dickens cover.
Some of the other pairings are shown here: 'Crime' (Dostoevsky and Highsmith), 'Lust' (Fielding and Amis) and 'Sin' (Dante and Roth). I think they're all quite effective.
