The poster for Proof turned out to be quite a challenge. Another play that has a stigma attached to it - since it's about a mathematical proof, people expect to see, well...numbers. After talking it over with the director, I decided to hand write actual proofs to create the title of the play. We wanted to convey the questioning that is present throughout the play as well as the look of notepaper that has been sitting, forgotten in an office for years.
My regret on this poster is that in all the hours I spent copying down proofs, none of it osmosed into my brain. It still all looks like an alien language to me.
Ah well. We can't all be mathematical geniuses.
