I enjoyed reading this book, which provides a heavily-illustrated history of Penguin book covers from 1935 to 2005. There are a lot of wonderful covers here. The original penguin logo was adorable. At the back of the book, there's a listing of the logos from over the years, and the first penguin is definitely my favorite.
It's great to look through and see covers from some books I have. There's a nice tactile quality to the design of this book that dovetails nicely with the subject at hand.
My only complaint is that the side notes in the useful chapters on the history of Penguin are in orange and are hard to read. I get why they chose orange, but that doesn't help my eyes to read it. But that's a minor point.
A neat, fun read on Penguin's own history and British design more broadly.
