If you’ve been watching Mad Men the past few years, you may have seen illustrator Pete Hawley’s work without even knowing it. Wilbur “Pete” Hawley was a mid-century illustrator known for his Jantzen pin-ups and 50′s era advertising work to movie posters and American Greeting Card Company cards. He was a master of capturing the classic smirk and eye-twinkle that permeated mid-century advertising, and provided much of the inspiration for our own Sophie the Scibbler. You’ll see his work falling in the opening credits of Mad Men. Check out more of Pete’s work here.
