This jigsaw puzzle offers a fascinating glimpse into the infrastructure of a busy city, with both underground and above-ground scenes to explore. Kids can discover subway cars, pipes, construction sites, and other details of urban life in Linda Bleck’s colorful illustrations. The puzzle includes 48 large, glossy pieces that fit together easily, along with a 16" x 20" informational poster. When completed, it measures 30 x 24 inches—big enough for floor play—and comes in an 11" x 11" x 2" box. Designed for ages 4 and up, it’s a high-quality observational puzzle that encourages focus and learning. Like all eeBoo products, it provides screen-free fun while fostering conversation and skill-building, continuing the brand’s 25-year tradition of educational play.
