Two detailed scientific sketches of oyster shells rendered in graphite reveal the mollusk's internal and external structure with careful anatomical precision. The warm cream paper grounds these naturalistic drawings, capturing the ridged texture of the shells and their organic, asymmetrical forms through delicate cross-hatching and subtle shading. 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.
