Seven sleek bullet trains are stacked in horizontal formation, each rendered in precise line art with distinct color schemes ranging from turquoise and white to navy and gold. The composition captures the evolution of Japan's legendary Shinkansen across decades, from the streamlined 0 Series at top to modern variants below, set against a cream ground with a bold Japanese flag and "新幹線 SHINKANSEN" text anchoring the lower left. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
