Five Clouds To Know

A vintage field-guide poster presents five cloud types as watercolor studies stacked on cream paper. Bold slab-serif lettering announces FIVE CLOUDS TO KNOW. Thin leader lines run from a left-edge altitude scale to each form: high, wispy cirrus of ice crystals; a muted grey altostratus sheet; a puffy low cumulus of fair weather; a flat stratus fog bank; and a towering cumulonimbus stained with ochre, labeled for thunderstorms at all levels. Washes of sky blue, slate, and warm ochre sit against aged paper with faint foxing. The palette stays muted and documentary, echoing mid-century meteorological charts rather than decorative illustration. Lighting is even and paper-bound, with no dramatic sky; the mood is instructional, calm, and slightly nostalgic. Composition is strictly vertical and didactic, each cloud occupying its own register so the eye reads altitude as a sequence. The work sits between scientific plate and gallery print: precise enough to teach, painterly enough to linger.
