46. Shhhhhh Cards.
From the "I wish I had done that" department comes Shhhh Cards from Coudal Partners, a design and advertising agency/studio in Chicago. They don't go around telling everyone how creative they are - they keep themselves busy actually being creative. Kudos. (Have I mentioned that I really, really wish I would have done these?!?)
