Prompt
"Create an image of a vintage book cover for a classic children's novel, set against a backdrop of a London cityscape in the 1930s. The cover features the title 'Mary Poppins' in bold, playful lettering, with an illustration of a magical and mysterious woman in a long, flowing coat and hat, standing with an umbrella. The style should be reminiscent of classic children's book illustrations from the early 20th century, with a mix of realism and whimsy. The color palette should be muted, with a focus on earth tones and pastels."
