Ernst Haeckel Sea Squirts — Illustrated Postcard

Soft teal and cream sea squirts branch and cluster across this postcard, drawn in Ernst Haeckel's meticulous naturalist style with frilled crowns, coral-like growths, and delicate ribbing.

A gentle, pastel counterpart to his brighter plates — a good pick for a quieter note or a marine-biology-themed collection.
