This is a vintage illustration of an onion. The onion is depicted in shades of purple and black, with vertical stripes suggesting its layers. It has a cluster of green leaves sprouting from the top and thin, white roots extending from the bottom. The onion sits on a bright green, slightly undulating surface, resembling a grassy mound. The entire image is framed by a rectangular border with a warm, golden hue. The style of the illustration is reminiscent of botanical or herbal drawings from historical texts, with a focus on accurate representation and a slightly naive aesthetic.
