A tall vertical decorative panel illustration in late-nineteenth-century Art Nouveau style, centered on a single peacock with its tail unfurled in a stylised sweeping S-curve. Linework is fluid, varying in weight, with whiplash curves typical of the movement. Negative spaces are filled with stylised pomegranate flowers, curling tendrils, and a few hand-drawn six-petalled rosettes. The peacock's body is drawn in confident dark outline, with body feathers suggested by short rhythmic strokes, while the tail eyes are concentric ovals filled with patterns rather than realistic shading. Behind the bird, a faint half-circle motif acts like a halo. The palette is limited to muted peacock teal, antique gold, deep aubergine and warm bone white, with the gold used sparingly as solid fills inside the tail eyes and along a thin border. The vertical border itself is a slim repeating geometric chain. At the bottom of the panel, an inset banner of small ornamental serif text reads "PAONNE" in spaced capitals. No modern digital gradients, no airbrush — flat color fills inside confident ink contours, as if drawn for a Parisian boutique poster of the 1900s.
