Anne Healey at the Thomas Riggs & Co blog found these via Première de Couverture. They're a series of collages done as covers for Les Éditions Les Allusifs, a Canadian publisher of literature translated into French.
They're the work of Alain Pilon, who has a whole mess of stuff at his website. Here are some more of his Allusifs.
Again I find myself wishing I could speak French, so that I could justify buying a few of these suckers.
UPDATE: The multi-talented Ian Shimkoviak informs me that the design agency responsible for putting these together has an excellent website here. And he's right!
