I could have sworn I posted about this earlier, but perhaps I only meant to. Vogue covers from 2010 overlaid on each other. Interesting how Vogue in different countries styles itself. Some, like the US have a very consistent format, allowing an image to form in the center of the overlay with the text stacked neatly on the sides. Others, like Vogue Paris, seem to take more risks from cover to cover. All 14 covers together form a very clear image.

No longer sure where I first saw them, it may have been Jezebel.com but images are all from LiveJournal.
