I love when a friend surprises me with a book, especially when it's one I haven't seen. Recently, Judi gave me this one - Playful Type, which is soon to come out in paperback. If you enjoy lettering of all kinds then you might want to give this one a peek.
Also about to launch: Illusive 3. I loved 1 & 2 so I will totally get 3. I really enjoy these publications from Gestalten.com as they are simply full of art, no wordy explanations. They give us views of artists who we might not otherwise meet, and leaves it up to us to further investigate, if interested, through the resource page.
