With his upturned nose, thick-rimmed glasses, bow tie, and petite yellow hat, Young Frank is both sophisticated and childlike, experimenting with everyday materials under the watchful eye of his namesake architect grandfather. Not a Frank goes unnoticed as the unusual pair explores the Museum of Modern Art. The trip is educational for both, exposing the creativity involved in building design. Rust oranges, olive greens, and lavender blues give a distinguished atmosphere to this imaginative book. Ages four to eight.
