A vertical classroom-poster chart of ten common cloud types, painted in soft gouache on faintly off-white paper. The vertical axis on the left marks altitude in two systems: meters on one side and feet on the other, ranging from ground level up to 12000 m. Three altitude bands are tinted very lightly: "High clouds 6000-12000 m", "Mid clouds 2000-6000 m", "Low clouds below 2000 m". Painted cloud studies float at correct heights, each labelled in lowercase italic Latin and English: "cirrus", "cirrostratus", "cirrocumulus", "altostratus", "altocumulus", "nimbostratus", "stratus", "stratocumulus", "cumulus", "cumulonimbus". Tiny one-line descriptions in dark teal explain shape and weather hint, e.g. "cirrus: thin streaks, fair weather, often before a front". A title at the top reads "A Field Guide to Common Clouds". Lower-right corner has a small painted person with arms raised for scale. Soft pigments, visible brush texture, a few pencil tick marks, generous whitespace, no digital gradients.
