Serre botanique · Affiche de voyage mid-century

Retro vintage poster artwork of a grand botanical glasshouse with palm fronds pressing against the dome, as a mid-century travel poster with flat gouache shapes and sunny colors. Bold simplified shapes, a limited color palette, halftone texture and aged paper grain, strong graphic composition. Purely visual: no text, no lettering, no numbers, no logos. Vertical 4:5.
