Overlapping circular postmark stamps from vintage Tokyo crowd the composition in a repeating pattern, their detailed Japanese characters and postal marks rendered in grayscale linework. The dense, layered arrangement creates a sense of accumulated history and correspondence, with each stamp partially obscuring others to form an intricate visual texture across a light ground. 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.
