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.
