This whimsical children's book by award-winning author and illustrator Frank Viva explores MoMA's collection through the adventures of Young Frank, an aspiring architect, who lives in New York City with his grandfather, Old Frank, also an architect. Young Frank likes to use anything he finds—macaroni, pillows, toilet paper, shoes—to make buildings that twist, chairs with zigzag legs, and even entire cities. But Old Frank disapproves, saying architects only create buildings. One day they visit The Museum of Modern Art, where they see work by architects Frank Gehry, Frank Lloyd Wright, and many others, and Old Frank learns that architects can do more than he thought. The Franks go home and create structures of every shape and size, using whatever they can get their hands on, even cookies. At the end of the day, Young Frank feels a little older, and Old Frank feels a little younger—and a little wiser.
