Two human skulls rendered in precise anatomical detail occupy a black ground, their surfaces etched with Latin labels identifying every bone, ridge, and cavity from multiple angles. The grayscale engraving technique creates a clinical yet dramatic study, emphasizing the geometric structure of bone through fine line work and subtle shading that gives the forms sculptural weight. 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.
