A cross-sectional diagram of an oyster rendered in sepia ink on cream paper reveals the creature's internal anatomy with meticulous detail, from the ridged shell exterior to the delicate gill structures and soft tissues within. The naturalistic scientific illustration employs fine line work and subtle shading to create depth and texture, presenting the subject with both scientific precision and quiet elegance. 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.
