Last summer, I received a phone call from Michael, a designer from mgmtdesign in Brooklyn, New York. After the initial how-do-you-do’s, he explained that they were designing a new book for Al Gore, Our Choice, the sequel to An Inconvenient Truth.
“Great project”, I said.
And it got even better. They had chosen Brioni, one of our typefaces, for the body text.
“And this is why I am calling now”, said Michael, his voice dropping a level. “You see, Al is really involved with the project and we spend a lot of time working together in the publisher’s office. When he was reviewing the proofs, he had a comment about the typeface.”
I took a deep breath and asked what the comment was.
“Basically, he wants you to change the numeral one.”
It turns out the numeral 1 looked more like a Roman numeral (I), which caused some confusion when paired with capitals, so the font designer touched up the number 1 so it looked more traditional.
Fun story; I can't imagine very many times where an ex-Vice President (and Noble Prize winner) calls regarding a font, nevermind "I like your font so much that I'm going to use it, but the number 1 really isn't working for me."
