Six porpoise species swim across a soft periwinkle ground, each rendered in deep purple tones with distinct anatomical details that make them instantly recognizable. The composition arranges them in a scattered, naturalistic layout that feels both educational and playfully whimsical, with each creature labeled below. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
