John Self of Asylum, probably the internet's best collection of book reviews, kindly pointed out to me another of these two-covers, one-image occasions.
The first is Leonid Tsypkin's novel about Dostoevsky on a gambling binge, Summer in Baden-Baden, a book I really, really wanted to like but had a great deal of trouble getting into.
The second is the new Vintage Classics editions of Somerset Maugham's thoroughly entertaining and faintly mad The Magician, a science-fantasy riff on the life of self-proclaimed "wickedest man alive" and proclaimed-by-me "tedious wanker" Aleister Crowley.
The original is a Pernot ad by Leonetto Cappiello.
Mysteriously, the Penguin Tsypkin cover has removed the label from the bottle.
There's more on Cappiello and absinthe in an earlier post, here.
UPDATE: Now we're seeing triple...
