Vintage cookbook illustration of a creamy banana smoothie

A vintage-style cookbook illustration of a creamy banana smoothie in a tall glass jar with a metal straw, topped with a light sprinkle of cinnamon. The smoothie has a smooth, thick texture with a subtle swirl of peanut butter visible. Surrounding the glass are ingredients like a peeled frozen banana, a small bowl of peanut butter, and a cinnamon stick, all arranged on a rustic wooden surface. Warm, neutral earthy tones with soft shading and fine ink-like line work, reminiscent of hand-drawn 1950s recipe book illustrations. White background with a clear space at the top for recipe title placement.
