There are a plethora of sites out there that showcase lovely bits of graphic design, and an increasing number of those are devoted to the world of cover design. (See our earlier post.)
FaceOut Books, from the Oregon design studio The Design Works Group, takes this a step further though, and looks in detail at the process of creating those covers. They post regularly each Monday, and have quickly created a real treasure trove of delights.
Really great and worth taking some time out to have a look through.
