A deceptively simple, decidedly playful sequence of statements invites readers to ponder, what comes first: the chicken or the egg? Carefully choreographed page turns and die-cuts focus on the process of change and becoming, so “First” sits alone on a yellow background, facing “the EGG”—an egg-shaped die-cut revealing a white egg against an orange-and-brown background. Turn the page, and “then” appears, the egg-shaped die-cut now forming the yellow body of a chick emerging from the shell, facing “the CHICKEN”—the white hen whose body gave color to the previous spread’s egg. Tadpole and frog, seed and flower, caterpillar and butterfly all receive the same treatment, then word and story, paint and picture bring all the disparate elements together, nature being the catalyst for art. Seeger’s vibrant, textured oil-on-canvas illustrations contain a wealth of subtlety, allowing the die-cuts to reveal cunning surprises with each turn of the page. Children and adults alike will delight in flipping the sturdy pages back and forth to recreate the transformations over and over again. Another perfectly pitched triumph from an emerging master of the concept book. (Picture book. 2-6)
