Cy Twombly's *Natural History Part I: Mushrooms* is a complete set of ten lithographs combining collotype in colors with collage and delicate touches of hand-coloring on Rives Couronne paper. The works reflect Twombly's characteristically poetic sensibility, merging botanical imagery with his loose, gestural mark-making and handwritten text to evoke a sense of organic growth and mythological resonance. The layered techniques — printmaking, collage, and hand-coloring — create richly textured surfaces that blur the boundary between fine art and natural specimen study.
