Waves of petals

Three koi (a black-and-gold, a green, and a rust-orange fish) swim diagonally through dark teal water blanketed with pale pink and cream petals, their bodies half-obscured beneath the drifting petal pattern. The dense, all-over scattering of petals across the water's surface flattens the composition into a repeating textile-like design, with only the fishes' curved forms and dark scale-outlines breaking the pattern. Signed "Shiro Kasamatsu" in the lower right with a red seal; a woodblock print titled "Waves of petals," dated 1956 in the margin below the image.
