Penguins by the dozen.

Penguin books have been around for ages and can be found all over the world in all types of books shops. via Cool Hunting I found designer Joe Kral. Now Joe Krals connection to Penguin is that he collects them (mainly from the 60s and 70s) and posts them on his online collection, showing off the bold retro graphics and great illustrations. Buying books solely for their covers...hmm that is quite a cool hobby. Check out all the great covers he has collected here!
