A square reference poster shaped like a stylised tree showing a simplified Indo-European language family. Warm parchment-cream background with deep olive-ink linework, drawn as if hand-engraved with a thin nib. The trunk is labelled "Proto-Indo-European, c. 4500 BCE". From it grow ten main branches, each ending in leaves that carry language names in small caps: "Sanskrit", "Hindi", "Persian", "Greek", "Latin", "Italian", "Spanish", "French", "Old English", "German", "Dutch", "Russian", "Polish", "Lithuanian", "Irish", "Welsh". Sub-branches show family group titles inside ribbons: "Indo-Iranian", "Hellenic", "Italic / Romance", "Germanic", "Balto-Slavic", "Celtic". A tiny compass rose sits lower-left; a legend lower-right explains "Solid line: direct descent" and "Dashed line: heavy borrowing". Title across the top reads "A Family Tree of Indo-European Languages". A footer note reads "Simplified for teaching, not exhaustive". Crosshatched shading on the trunk, decorative oak leaves at the corners, no color other than ink and parchment, ample airy margins.
