Jessica Helfand and William Drenttel dug deep into their library of more than 10,000 volumes to find examples both seminal and surprising for an issue's primer on graphic design. The couple are partners at Winterhouse, a studio in northwest Connecticut that produces books, magazines, and websites. When they're not making maple syrup, Helfand can be found evangelizing scrapbookers on the glories of photomontage(her new book, Scrapbooks: An American History, was published in November of 2008) while Drenttel keeps himself occupied with fixing education and conquering world poverty. They don't sleep much.
