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 to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
