Trying to sit in a tiny adjustable office chair at a modest work desk, its long neck rising far above the desk while it calmly adjusts the chair lever. The real Argentinosaurus (say it ar-jen-TEEN-oh-SORE-us) lived in the Late Cretaceous — possibly the heaviest land animal that ever lived, around seventy tonnes. Painted in the Storybook style: soft gouache and colored pencil over an anatomically careful drawing — gentle enough for a nursery, accurate enough for a classroom. Die-cut matte vinyl in three sizes; the laminate shrugs off rain, dishwashers and backpack abuse.
