The image is a cyanotype of a piece of seaweed. The seaweed is a pale, almost white color, and it is arranged in a branching pattern. The background is a deep, rich blue. At the bottom of the image, there is a label with the scientific name of the seaweed, 'Halymenia ligulata var. latifolia', written in a delicate script. The overall effect is reminiscent of a botanical illustration or a vintage scientific specimen.
